Answer:

a. S = 3n + 2

b. There while be 62 squares.

Step-by-step explanation:

We know the first term of this sequence is 5. To figure out the equation, subtract the following term from the previous. Do you see a common difference?

8 - 5 = 3

11 - 8 = 3

14 - 11 = 3

We're seeing a constant difference of 3 (which makes this an arithmetic sequence), but the first term is 5. That mean something is being added to make the first term 5. Subtract 3 from 5 to get 2. This means 2 is being added to every multiple of 3, which leads us to the equation: S = 3n + 2.

To find the 20th term of this sequence, substitute n for 20 and do the operations.

S = 3(20) + 2

<em>Multiply 3 by 20, then add 2.</em>

S = 62

The 20th term will have 62 squares.

$\frac{13-b}{6}= \frac{2-0.5b}{4} \\ 4(13-b)=6(2-0.5b) \\ 52-4b=12-3b \\ b=40$
