Question

The mean of the first ten consecutive odd numbers is:

• A. 100
• B. 10
• C. 50
• D. 20

Hint:

The mean of a set of consecutive odd numbers can also be calculated by taking the average of the first and last terms.

Answer 1

The Correct Option is B

The first ten consecutive odd numbers are: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19. The sum of these numbers is: \[ 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100 \] The mean is calculated as: \[ \frac{\text{Sum of numbers}}{\text{Number of terms}} = \frac{100}{10} = 10 \] Thus, the correct answer is \( \boxed{10} \).
