Use the mathematical induction to prove the following statement. Homework Help ✎

1² + 2² + 3² + … + n² =

Step 1:

Step 2:

Step 3:

1² + ... + k² + (k + 1)² =

So the induction step is true.

Step 4:

Since we know the statement is true for n = 1 and the induction step is true, we know that the statement is true for all positive integers n.
