Find the sum of all odd numberbetween 0 and 50​

Answer»

bers between 0 and 50 are 1, 3,5,7,9,11,13,15,17,19,21,23,25,27,29,,31,33,35,37,39,41,43,46,48,49.
We can make pares of the least and the highest NUMBERS. For example - 1 + 49, 3+47 ……… and so on.
Thus each pare will add up to 50.
There are a TOTAL of 12 whole pares + 25

= 12 (50) + 25
= 600 + 25
= 625
