Question

the average of 100 numbers

Answer 1

use the formula n(n+1)/2
n=any natural number

Answer 2

The no.s are not specified.
I think the question is Avg of 10 Natural no.s


Avg= sum/No.

Sum of n Natural no.s = 1/2(n(n+1))
Sum of 100 Natural no.s will be
1/2(100(100+1))
=50(101)
=5050

Here No. = 100
Avg = 5050/100= 50.50

;)
Hope it helps
