Question

The list of numbers 5, - 2, -9, -16 ... is an AP with d = 7.

• A. An AP with d = -7
• B. An AP with d = 7

Answer 1

The correct option is B An AP with d = 7

We know that for a sequence to be an AP, the same common difference must exist between any two consecutive terms of AP.
Here in the given list of numbers, we can easily see that between any two consecutive terms there exists the same difference of -7. Hence the numbers are in AP.
