Question

6. Does the sequence-1.-1.-1.--1. ... form an AP? Justify your answer​

Answer 1

Answer:

We can say that a series is in AP only when it follows the rule of common difference I.e. (a2- a1) must be equal to (a3-a2) and here also this rule is followed by the series as a2 minus a1 is equal to as3 minus a2 I.e.0 hence this series can also be an AP as it follows the rule of common difference.
