Sequence

Find the common difference and a formula formula for the nth term of the arithmetic sequence; 6, 2, -2, -6, -10,...a sub n =

a)6-4n
b)6-2n
c)10-2n
d)10-4n

I think it is c but want to check.

Ao is 10, then each term subtracts 4n from it....n=1, ...

well if 6 is equal to the first term of the sequesnce the only one that would work would be d.

1st = 6 so 10-4(1)=6 where n is the number of the term

2nd = 2 so 10-4(2)=2

3rd term = -2 so 10-4(3)=-2

Hope that helped.
