The average of first 50 natural numbers is …………. .

Answer» \bold{Answer :}

The first 50 natural numbers are

1, 2, 3, ..., 50

So, the 1ST term (a₁) = 1,

the last term (a₅₀) = 50

Then, the sum of 1st N = 50 natural numbers be

= n/2 * (a₁ + a₅₀)

= 50/2 * (1 + 50)

= 25 * 51

= 1275

Hence, the average of 1st 50 natural numbers be

= 1275/50

= 25.5
