 # How Many Ways Are There To Add Four Positive Odd Numbers To Get A Sum Of 22?

## What is the formula for sum of odd numbers?

What is the sum of odd numbers from 0 to 50.

If the number is starting from 1 then you can do simply n^2.

for example: if n=6 like 1,3,5,7,9,11 then it’s sum will be 6^2=36.

But if odd number series not start from 1 then formula will be sn=n/2(2a+(n-1)d)..
