How many numbers are in the list \($2008, 2003, 1998, \ldots, 8, 3?$\) ?

I think the answer is 401.2 but im not sure

I count 5....but I'm not sure.

The number of TERMS in the ARITHMETIC series:

(2008 -3)/5 + 1 = 402

Last term = First term - 5( N - 1) where N is the number of terms

3 = 2008 - 5(N - 1) subtract 2008 from both sides

-2005 = -5N + 5 subtract 5 from both sides

-2010 = - 5N divide both sides by - 5

402 = N
