The explicit rule for an arithmetic sequence is an = -4 + (n - 1)7.

what is the common difference of the arithmetic sequence?
d =

The common difference of the arithmetic sequence is 7.

Step-by-step explanation:

The explicit rule for an arithmetic sequence is

           .... (1)

where, a is first term of an AP and d is common difference.

The given explicit rule for an arithmetic sequence is

             .... (2)

From (1) and (2), we get

It means the first term of the arithmetic sequence is -4 and the common difference is 7.

Therefore the common difference of the arithmetic sequence is 7.

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

i think is g(1)=-1.

hope that i can
