Answer to Problem 1CFU

The $n+1$ case shows that the conjecture is true of an infinite number of cases including all values of $n$ .

Explanation of Solution

Given information:

In the process of mathematical induction, it is necessary to prove the $n+1$ case.

Calculation:

In the process of mathematical induction, it is necessary to prove the $n+1$ case because it shows that the conjecture is true of an infinite number of cases including all values of $n$ .
