2. A sequence qn is defined by q1 = 1 and qn+1 = 2qn+2" for all n ≥ 1. Suppose you want to prove the formula qn = n.2n-1 by induction on n. In your induction step, what algebraic identity will you have to prove? (You don't actually need to prove anything or check any identities to answer this problem; just give the algebraic identity that the proof woul need.)
