Question

Find the average of first 5 odd numbers.
1. 4
2. 5
3. 6
4. 3

Answer 1

Correct Answer - Option 2 : 5

Formula used:

Average = (Sum of observation)/(Number of observation)

Calculation:

First 5 odd numbers are (1, 3, 5, 7, 9).

Average = (1 + 3 + 5 + 7 + 9)/5

⇒ Average = 25/5

⇒ Average = 5

∴ The average of first 5 odd numbers is 5.
