Which of the following is the general term for the sequence m, -m, m, -m, . .?

nth term formula is

Step-by-step explanation:

the sequence m, -m, m, -m, . .

The difference between the terms is 0 . so lets find the common ratio

To find common ratio , divide the next term by previous term

Common ratio -1. It is a geometric sequence

General term for the sequence is

where a1 is the first term and 'r' is the common ratio

a1=m , r=-1

the answer is c)8
