Sum of first n odd natural numbers = n2.
So, the arithmetic mean of first n odd natural numbers = n2/n = n.
Here n = 20.
∴ the arithmetic mean of first 20 odd natural numbers = 20.
So, the arithmetic mean of first n odd natural numbers = n2/n = n.
Here n = 20.
∴ the arithmetic mean of first 20 odd natural numbers = 20.
