the first 5 terms of a linear sequence are given below: 8,6,4,2,0...
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.

term(n) for an arithmetic sequence is (a+(n1)d )
your a=8, d=2 , n=100
term(100) = a + 99d
= 8 + 99(2) = 190
