Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Let P(n) be the statement that 13 + 2 + 33 + for the positive integer n. 2 n(n+1) = Complete the inductive step, identifying where you use the inductive hypothesis. (You must provide an answer before moving to the next part.) Multiple Choice O Replacing the quantity in brackets on the left-hand side of part (c) by what it equals by virtue of the inductive hypothesis, we have (k+1+2) = + (2+1) = as desired. O Replacing the quantity in brackets on the left-hand side of part (c) by what it equals by virtue of the inductive hypothesis, we have (1)+(x+1)=(x+1)= +1x+2) as desired. Replacing the quantity in brackets on the left-hand side of part (c) by what it equals by virtue of the inductive hypothesis, we have (+1)+(k+1)=(+1()=() as desired. Replacing the quantity in brackets on the left-hand side of part (c) by what it equals by virtue of the inductive hypothesis, we have (411)+(k+1)=(k + 1 (A) as desired
