Problem 1: (15 points) Consider the sequence given by an = n(n+1) and the series S₁ = [194. (i) Write out sn for n = 2,3,4,5, simplifying where possible. (ii) Use your answer from (i) to come up with a general formula for the series Sn. (iii) Prove by induction on n € Z+ that your formula is correct.
