c. 7

Answer 1

b. -7
This will be common difference of this sequence
it is such an easiest question

Answer 2

Common difference is -7.

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)`

Where,
`a_(1)` is the first term and
`a_(1)` is the second term.

Then common difference = 49 -56

= -7 .

Therefore,b) common difference is -7.
