find the average of first 40 natural numbers
Answer: To find the average of the first 40 natural numbers, you can use the formula for the average:
Average = (Sum of Numbers) / (Number of Numbers)
In this case, the first 40 natural numbers are 1, 2, 3, …, 40. You can use the formula for the sum of an arithmetic series to find the sum of these numbers:
Sum = (n / 2) * (first term + last term)
where n is the number of terms and the first term is 1 and the last term is 40.
So, Sum = (40 / 2) * (1 + 40) = 20 * 41 = 820.
Now, you can find the average:
Average = Sum / Number of Numbers = 820 / 40 = 20.5.
The average of the first 40 natural numbers is 20.5.
