Question

Mean of first 5 natural numbers:

• A. 2
• B. 3
• C. 4
• D. 5

Hint:

For any sequence of numbers with a constant gap (like 1, 2, 3, 4, 5), the mean is always the middle term!

Answer 1

The Correct Option is B

To find the mean of the first 5 natural numbers, we start by listing these numbers. The first 5 natural numbers are: 1, 2, 3, 4, and 5.

The formula to calculate the mean (average) is:

\(\text{Mean} = \frac{\text{Sum of all values}}{\text{Number of values}}\)

Let's apply this formula:

1. Calculate the sum of the first 5 natural numbers: \(1 + 2 + 3 + 4 + 5 = 15\)
2. Count the number of natural numbers which is 5.
3. Calculate the mean: \(\text{Mean} = \frac{15}{5} = 3\)

Therefore, the mean of the first 5 natural numbers is 3.

The correct answer is 3.
