The first term of an arithmetic sequence is 10 and its common difference is

negative seven. What is the fourth term of the sequence?

The fourth term is - 11

Explanation:

a. p = a1 + (n-1) d

a. p = 10 + (4-1) - 7

a. p = 10 + (3) - 7

a. p = 10 - 21

= - 11

a1 = first term

n = nth term

d = difference
