This was the extra credit question on a quiz I had today, I am very anxious to find out the answer.
1. Homework Statement
Find the apparent Nth term of the sequence
2,-5,10,-17 ... n
2. Homework Equations
Not sure really on this
an = ...
3. The Attempt at a Solution
(n)+(2n-1)*(-1)^(n-1)
The sequence starts with 2 and then increases by sequential odd numbers and alternates positive and negative.
Thanks very much
