Question

Find the mean ( average ) of first 5 natural numbers​

Answer 1

Answer:

Let we have five consecutive natural numbers = x , x + 1 , x + 2 , x + 3 , x + 5

And as given average of these numbers = 75 , So

x + x + 1 + x + 2 + x + 3 + x + 45 = 75

5x + 10 = 375

5x = 365

x = 73

So,

Numbers are 73 , 74 , 75 , 76 , 77
