Can you please explain what the right side should be to prove this statement? I'm very confused by the two variables. 

 

Prove the following statement by mathematical induction. n+1 For every integernz 0, Fi.2' = n: 2" + 2+ 2. i = 1 Proof (by mathematical induction): Let P(n) be the equation n+1 Si:2' = n 2' + 2. i= 1 We will show that P(n) is true for every integer n 2 0. Show that P(0) is true: Select P(0) from the choices below. 0 + 1 - 21 +2 + 1. i = 0 2 O 2 = 0- 2" + 2 + 2 0 + 1 Oi: 2 = 0 - 20 + 2+ 2 i = 1 n + 1 Ei.2' = 0. 20 + 2+ 2 i = 1 The selected statement is true because both sides of the equation equal the same quantity. Show that for each integer k 2 0, if P(k) is true, then P(k + 1) is true: Let k be any integer with k z 0, and suppose that P(k) is true. Select the expression for the left-hand side of P(k) from the choices below. k+1 i = 1 k+1 i = 1 k+1 Σ i= 1 k+1 The right-hand side of P(k) is (i+1) · 2(?+1)+2+2 IThe inductive hvpothesis states that the two sides of P(k) are equal.1
