Question

Find the 32nd term in the sequence whose general term is an = -3 + 4 (n-1)

Work?

Answer 1

121

Explanation:

To find the 32 nd term substitute n = 32 into the general term formula

`a_(32)` = - 3 + (4 × 31) = - 3 + 124 = 121

Answer 2

121

Explanation:

T32 = -3 + 4 (n - 1)

Let n = 32

T32= -3 + 4 (32 - 1)

= -3 +4(31)

= -3 + 124

= 121
