Answer 2

Given,

Series have 6 multiples of 6

To Find,

Mean of given series=?

Solution,

First 6  multiples of 6 are  6 , 12 , 18 , 24 , 30 , 36

Total number of elements = 6

From the formula of mean, we know that,

Mean  = Sum of all observation / Total observations

Mean = (6 + 12 +18 + 24 + 30 + 36)/ 6

Mean = 126 / 6

Mean =  21

Hence, mean of first six multiples of 6 is 21
