Find The Arithmetic Mean Of The First 7 Natural Numbers.

Answer»

The first 7 natural numbers are 1, 2, 3, 4, 5, 6 and 7.

Let x denote their ARITHMETIC MEAN.

Then mean = Sum of the first 7 natural numbers/number of natural numbers

x = (1 + 2 + 3 + 4 + 5 + 6 + 7)/7

= 28/7

= 4

HENCE, their mean is 4.

The first 7 natural numbers are 1, 2, 3, 4, 5, 6 and 7.

Let x denote their arithmetic mean.

Then mean = Sum of the first 7 natural numbers/number of natural numbers

x = (1 + 2 + 3 + 4 + 5 + 6 + 7)/7

= 28/7

= 4

Hence, their mean is 4.
