Question

Find the mean of first eleven natural number

Answer 1

Answer:

The first natural numbers are 1,2,3,4,5,6,7,8,9,10,11 and the average value or the mean of the first 11 numbers would be 6

Step-by-step explanation:

1+2+3+4+5+6+7+8+9+10+11 = 66

then 66/11 = 6.

where 66 is total sum of numbers

and 11 is total numbers.

Answer 2

Answer:

sum of first n natural numbers=n(n+1)/2

sum of first 11 natural numbers

n=11

=n(n+1)/2

=11(11+1)/2

=11x12/2

=132/2

=66

sum of 11 natural numbers=66
