Find the common difference for the sequence shown.
56, 49, 42, 35,
-12
-7
7

The common difference is -7.

Step-by-step explanation:

Given sequence,

56, 49, 42, 35,

Which is an Arithmetic sequence ( because consecutive terms are in same difference ),

Since, the difference between the consecutive term is called the common difference,

Thus, common difference,

d = 49 - 56 = 42 - 49 = 35 - 42 = -7
