-10, -14,18,-22 what's the explicit formula that can be used to determine the 9th term in this sequence A. A(n)=-4n-6 C. A(n)=n-10 B. A(n)=-4n-14. D. A(n)= n-4

Step-by-step explanation:

Given

Required

Determine the formula for the nth term

The sequence shows arithmetic progression.

So, we need to determine the common difference (d) first

In this case:

So:

The nth term is then calculated as thus:

what is the rest of the question? ?
