Use mathematical induction to prove that the statement is true for every positive integer n.4 +

+ . . . +
= 5
What will be an ideal response?
S1: | 4 ![]() ![]() |


4 = 4 ?
Sk: 4 +




Sk+1: 4 +




We work with Sk. Because we assume that Sk is true, we add the next consecutive term, namely

4 +






4 +





4 +

4 +





4 +




4 +




We have shown that if we assume that Sk is true, and we add
