Question

Find the sum of the odd numbers between 0 and 50.​

Answer 1

answer

we know

s=n/2 (a+l) -eq 1

• a=1
• l=49

n=l-a/d +1

• d=2

by solving this we get n=25 -eq 2

substitute n value in eq 1

from this we get the s value as 625

therefore the sum of odd numbers between 0 and 1 is equal to 625
