Question

Express $49$ as the sum of $7$ odd numbers.

Answer 1

Express the given number as the sum of $\mathbf{7}$ odd numbers:

The whole numbers, which can not be divided by $2$, are known as odd numbers.

Thus, $1,3,5,7......$ are odd numbers.

Now, the given number is $49$.

It can be expressed as,

$49=1+3+5+7+9+11+13$.

Hence, the given number can be expressed as $\mathbf{49}\mathbf{=}\mathbf{1}\mathbf{+}\mathbf{3}\mathbf{+}\mathbf{5}\mathbf{+}\mathbf{7}\mathbf{+}\mathbf{9}\mathbf{+}\mathbf{11}\mathbf{+}\mathbf{13}$.
