5,3,1,-1 find a^18

Answer:

**Arithmetic sequence 5, 3, 1, -1** then value of **a^18** is **3814697265625.**

**Solution:**

Given, **arithmetic sequence **is **5, 3, 1, -1**

We have to find the value of

We know that,** first term** of any A.P is represented by the letter “a”

So, here in our problem first term** a = 5**

Then we have to find the value of

Hence, the **value of a^18** is **3814697265625.**

Answer:
### Final answer:

### Explanation:

### Learn more about Arithmetic sequence here:

The 18th term of the **arithmetic sequence** is -29.

An** arithmetic sequence **is a sequence in which the difference between any term and its preceding term is constant. In this case, the common difference is -2, because each term is decreased by 2 to get the next term. To find the 18th term, we can use the formula:

**a****n**** = a****1**** + (n-1)d**

where **a****n** is the term we want to find, **a****1** is the first term, **n** is the position of the term, and **d** is the common difference.

Using the given sequence, we can substitute the values into the formula:

**a****18**** = 5 + (18-1)(-2) = 5 + 17(-2) = 5 - 34 = -29**

Therefore, the 18th term of the given arithmetic sequence is -29.

Is 7/20 equivalent to 7 hundreds

A square has sides of length s. A rectangle is 6 inches shorter than the square and one inch longer. What expression represents the perimeter of the rectangle?

Explain how you would order from least to greatest three numbers that include a positive number, a negative number, and zero.

At the end of a snow storm,Allison saw there was a lot of snow on her front lawn.The temperature increased and the snow began to melt at a steady rate.After the storm,the snow started to melt at a rate of 0.75 inches per hour and is known that 4 hours after the storm ended,the depth of snow was down to 9inches.Write an equation for the function S(t),representing the depth of snow on Allison lawn,in inches,t hours after the snow stopped falling

The answer would be eight peppers because there are eighteen peppers for every sixteen ears of corn so half of eighteen would be nine therefore eight ears of corn have been picked from nine peppers because nine is hald of eighteen and eight is half of sixteen

The **amount **of **pizza **that **Ruby **and **Angie **ate in all for this considered situation is given by: Option A: 8/15

Let we have to add two **fractions **as:

Then we will find **Lowest****Common Multiple **(LCM) of and . That will help to make the **denominators **same.

Once the denominators become same, the **numerators **can add up directly, giving us the **final****result **of **addition**.

So, we're specified that:

**Ruby**ate 1/3 of a pizza**Angie**ate 1/5 of the**pizza**

These 1/3 and 1/5 are parts of **pizza**.

If we add those parts which is **eaten**, we will get the total part of the pizza eaten.

Thus, we get:

Total part of the **pizza eaten **= (1/3 + 1/5) of a **pizza**.

The **least common multiple **of 3 and 5 is 15, because:

(see the multiples of 3 and 5. The first **common number **as both's multiple is the **least number **which is **multiple **of both, and is 15).

Thus, we get:

Thus, the **amount **of **pizza **that **Ruby **and **Angie **ate in all for this considered situation is given by: Option A: 8/15

Learn more about **fraction addition** here:

A = 8/15 of the pizza

Well, 1/3 + 1/5 = (5+3)/ 15 = 8/15

Well, 1/3 + 1/5 = (5+3)/ 15 = 8/15

**Answer:**

**137.5° and 42.5°**

**Step-by-step explanation:**

supplementary angles are two angles whose sum is equal to 180°.

Let the second angle be x then it is given that the first angle is 10 degrees more than 3 times second angle that is 3(x)+10°.

we know that the sum of first and second angles is 180° (supplementary angles)

so, (3(x)+10°)+(x) = 180°

4(x) = 170°

x = 170°/4 = 42.5°

so, first angle is 3(42.5°)+10° = 137.5°, second angle is x that is 42.5°

therefore, the angles are 137.5° and 42.5°.

Step-by-step explanation:

b. For a large family, is it possible that member would join for free? If so, which member would it be? Explain your reasoning.

c. Other than $0, what is the lowest amount that a member would pay to join? Which member would it be? Explain your reasoning.

**a. **If we subtract 75 from 550 twice, we get 400, which is the third member to join. Subtract 75 from 400, we get **$325, the fourth member to join.**

**b. **It is not possible that a member would join for free if it was a large family. 75 does not fit into 550 evenly. You can prove this by solving the expression 550÷75.

**c. **The lowest amount that a member would pay to join is $25.00. It would be the 7th member.

tim is saving to buy a new cell phone that costs $84. if he saves $12 each month, in how many months will he have $84?

well, divide 84 by 12

84/12 is 7. so, it will take him 7 months

84/12 is 7. so, it will take him 7 months
