What is the 100th term in the sequence?

A. -192

B. -190

C. -108

D. -90

I could figure this out in like 5 minutes, but I know there's a pattern I can't remember to figure it out quicker.

**Reiny**, Saturday, October 15, 2011 at 9:34amterm(n) for an arithmetic sequence is (a+(n-1)d )

your a=8, d=-2 , n=100

term(100) = a + 99d

= 8 + 99(-2) = -190
