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

Step 1: Understanding the Concept:
The Arithmetic Mean (Average) is the sum of all observations divided by the total number of observations.
Step 2: Detailed Explanation:
The first 5 natural numbers are: 1, 2, 3, 4, 5. Sum $= 1 + 2 + 3 + 4 + 5 = 15$. Total count $= 5$. $\text{Mean} = \frac{15}{5} = 3$.
Step 3: Final Answer:
The mean is 3.
