Find the common difference for the given sequence. Type a numerical answer in the space provided. Do not include spaces in your answer. If necessary, use the / key to represent a fraction bar. 56, 49, 42, 35, ...

Verified Answer :

The answer is -7....

Answer: -7

Step-by-step explanation:

  • The common difference of an Arithmetic progression is the difference between any two consecutive terms.

i.e. for sequence \(a_1, a_2, a_3 ,.....\)

Common difference = \(d=a_2-a_1=a_3-a_2=a_4-a_4\)

The given sequence : 56, 49, 42, 35, ...

Then , Common difference =\(49-56=-7\)

Hence, the  common difference for the given sequence. =-7
