Question

Given that `a_n = 3n - 5` , what are the 56th and 71st terms?

Answer 1

163 and 208

Explanation:

This is a great way to be given the general term of a progression!

`n` stands for the number of the term - in this case `n= 56 and n = 71`

TO find the value of the actual terms, substitute for `n`.

`a_56 = 3(56) -5 = 168-5 = 163`

`a_71 = 3(71)-5 = 213 -5 = 208`
