Question

What is the common difference between the terms in the following sequence?

{17, 11, 5, -1, -7...}
017
600 0
-5
-6
06

Answer 1

Since we're given that it's a arithmetic progression/sequence we can simply calculate the common difference by subtracting any 2 terms from the sequence.

`d = u_(2) - u_(1) \\ d = 11 - 17 \\ d = - 6`

Our common difference is:

- 6

Answer 2

-6

Explanation:

17-6=11

11-6=5

5-6=-1

-1-6=-7
