Question

What is the common difference of the sequence?

-19, -8, 3, 14, 25, ...

-------------------------

Answer 1

11

Explanation:

The common difference is the difference between any two consecutive terms. Pick any two consecutive terms, and subtract the first one from the second one.

25 - 14 = 11

14 - 3 = 11

3 - (-8) = 11

It is called the common difference because it is the same for all pairs of consecutive terms.

Answer 2

The common difference is 11, you can see this because the number goes up by eleven each time.
