Question

PLEASE HELP. An arithmetic sequence can be

modeled by the equation f(n) = -3+
7(n-1). What is the 72nd term in this
sequence

Answer 1

The answer is 494

Explanation:

`f(n) = -3+7(n-1) \\`

where

n is the nth term

From the question we are finding the 72nd term that's n = 72.

Substitute the value into the above formula and solve

That's

`f(72) = - 3 + 7(72 - 1) \\ = - 3 + 7(71) \\ = - 3 + 497`

We have the final answer as

494

Hope this helps you
