Answer:
This is a sequence, and the common difference is 7
Explanation:
Given
-13, -6, 1, 8, ...
A sequence simply is an ordered list of numbers.
To find the common difference, we find the difference between any consecutive terms.
-6 - (-13) = -6 + 13 = 7
1 - (-6) = 1 + 6 = 7
8 - 1 = 7
The differences between all the consecutive terms are the same, this is a sequence, and the common difference is 7
