Question

find sum of odd no b\w 0 and 50​

Answer 1

Using the sum of n consecutive integers formula, we can calculate the sum of 1 through 50: 50 x 51/2 = 25 x 51 = 1275

Answer 2

Answer:

Odd number between 0 and 50 are 1,3,5,7,9.....49

l=a+(n-1)d

49=1+(n-1)2

2n-2=48

2n=50

n=50/2

n=25

Sn=n/2(a+l)

=25/2(1+49)

=25/2(50)

=25(25)

=625.

Therefore the sum of all odd numbers between 0 and 50 is 625
