Question

Consecutive odd numbers whose sum is $5^3$ are

• A. 21,23,25,27,29
• B. 19,21,23,25,27
• C. 23,25,27,29,31

Answer 1

The correct option is A 21,23,25,27,29

To find the consecutive odd numbers whose sum is $5^3$, we first divide $5^3$ by 5.
$\Rightarrow \frac{5^3}{5}=5^2=25$
Since 25 is an odd number, it forms the middle number of the series.
The other odd numbers are the 2 odd numbers before and after 25.
So the odd numbers whose sum is $5^3$ are 21,23,25,27,29
