Mathematical induction proof for sum formula

[mr_coffee]

Directions: Evalute the sum, for n = 1, 2, 3, 4, and 5. Make a conjecture about a formula for this sume for general n, and prove your conjecture by mathematical induction.

StatusX helped me get the first part, so I know that is right, about making the conjecture.http://suprfile.com/src/1/3j13ycr/lastscan.jpg
