Question

The sequence of number -10 , -6 , -2 , 2 , ……. is * 2 points a) An AP with d = -16 b) An AP with d = 4 c) An AP with d = -4 d) Not an AP

Answer 1

B) An AP with d = 4

An AP is defined as a±d, a±2d, a±3d, ... , a±nd

And here,

-10 + 4 = -6

-6 + 4 = -2

-2 + 4 = 2

So This sequence is an AP with d = 4.
