Question

Find the sum of the odd number between 0 to 50​

Answer 1

Answer :

Step-by-step explanation:

The odd numbers between 0 and 50 are 1,3,5,7,9…49

Therefore, it can be observed that these odd numbers are in an A.P.

a=1,d=2,l=49

l=a+(n−1)d

49=1+(n−1)2

48=2(n−1)

n−1=24

n=25

Sn=2n(a+l)

S25=225(1+49)

=225×50=625

Answer 2

Answer:

THE ODD NUMBERS BETWEEN 0 AND 50

1,3,5,7,9,..….......49

THIS IS AN AP WITH COMMON DIFFERENCE 1 AND THE FIRST TERM 2

A≈1, D≈2,L≈49

L=A+(N-1)D

S25≈625
