Question

Find the average of first 100 natural numbers.

Answer 1

Given:—

• Find the average of first 100 natural numbers.

Now,

• Sum of first n natural numbers = 1/2 n(n+1)
• Sum of first n natural numbers = 1)2×100(100+1)
• Sum of first n natural numbers = 1/2× 100× 101
• Sum of first n natural numbers = 5050.

Therefore:—

• Their average = 5050/100
• Their average = 50.50

"Hence, their average will be 50.50."
