Find the common difference for the sequence shown.

56, 49, 42, 35, ...

-7

-12

7

(Maybe - 7) Bc 56-49=7 49-42=7 42-35=7 since it's goin backwards it should be (-7)

-7

Step-by-step explanation:

Given : sequence 56, 49, 42, 35, ...

To find : Find the common difference.

Solution : We have given that 56, 49, 42, 35, ...

By the common difference of an arithmetic sequence is:

d = a_{2} - a_{1}a2-a1

Where, a_{1}a1 is the first term and a_{1}a1 is the second term.

Then common difference = 49 - 56

= - 7.
