Question

D(1)=13
d(n)=d(n-1)+17
Find the 4th term

Answer 1

The 4th term is 64

Explanation:

This is a recursive formula. It tells us that the first term is 13 and that the common difference is 17.

d(1) = 13

d(2) = d(1) + 17 = 30

d(3) = d (2) + 17 = 47

d(4) = d(3) + 17 = 64

Answer 2

d (2)=d (1)+17=30
d (3)=d (2)+17=47
d (4)=d (3)+17=64
d (4)=64
