Problem 44: (Induction With Sum Of Odds)

Notice that $$ \begin{align} 1&=1 \\ 1+3&=4 \\ 1+3+5&=9 \\ 1+3+5+7&=16 \\ 1+3+5+7+9&=25. \end{align} $$ Make a conjecture about the sum of odd numbers by giving a general formula for what you see above. Then prove that your formula is valid by using mathematical induction.
