Question

Find the sum of all the first ‘n’ odd natural numbers.

Answer 1

Answer:

DaMEn It...I think So

Step-by-step explanation:

A.P(Arithmetic Progression), the sum of numbers is given by,

Sn=1/2×n[2a+(n-1)×d]

Where,

Sn= Sum of n numbers

n = n numbers

a = First term of an A.P

d= Common difference in an A.P

But, to find the sum of n odd numbers, there is a quick formulae,

Sn(odd numbers)= n²

For instance, what is the sum of first 10 odd numbers??

Here, n=10

Therefore, Sn=n²

Sn = 10²

Sn=100

Hope that helps!!
