Question

Complete the pattern:

$$\begin{gathered} 1+3=2\times 2 \\ 1+3+5+7=4\times 4 \\ 1+3+5+7+9+11= \end{gathered}$$

Answer 1

Finding the missing numbers:

By observing the pattern, we get

In this $1+3=2\times 2$, we can observe that there are two consecutive odd numbers started from $1$ so the result is $2\times 2$

In this $1+3+5+7=4\times 4$, we can observe that there are four consecutive odd numbers started from $1$ so the result is $4\times 4$

Therefore, In this $1+3+5+7+9+11$, we can observe that there are six consecutive odd numbers started from $1$ so the result is $6\times 6$

Hence, $1+3+5+7+9+11=6\times 6$
