Question 1. Consider the sequence b0 = 0, b1 = 1, and bi = (bi−1 + bi−2 + 1)/2 + 3(i − 1) for each integer i ≥ 2. Calculate the first few terms of the sequence, guess an explicit formula, and prove your explicit formula correct.

Challenge. Consider the sequence {ai} for n ≥ 0. Prove that if {ai} is both an arithmetic sequence and a geometric sequence, then it is a constant sequence (that is, a0 = a1 = a2 = …).
