Question

average of first 5 odd numbers​

Answer 1

Answer:

1 + 3 + 5 + 7 + 9 = 25

25/5 = 5

So 5 is the average of first 5 odd numbers.

Answer 2

Answer:

Mean=Sn, where S represents the sum of the observations and n represents the number of observations. ∴ the mean of the first five odd natural numbers is 5

First five prime numbers are 2, 3, 5, 7 and 11. The mean or the average formula is = Sum/no. = (2 + 3 + 5 + 7 +11)/5 = 5.6.
