Find the 5th term of the

sequence: - 8,-1, 6, 13 ...

20

Step-by-step explanation:

We need to determine what we are adding each time.

Take the 2nd term and subtract the first term

-1 - (-8)

-1 + 8 = 7

We add 7 each time

To find the 5th term, add 7 to the 4th term

the 4th term is 13

13+7 = 20

Step-by-step explanation:

a = - 8

d = - 1 - (-8) = 7

An = a + (n - 1) d

A5 = - 8 + (5 - 1) (7)

A5 = - 8 + 28
