The list of numbers 5, - 2, -9, -16 ...

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

Answer 1

Answer: (B), (C), (D)

The correct options are
B An AP with d = 7
C An AP with d = 3
D Not an AP

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 exist the same difference of -7. Hence the list of numbers are in AP.
