The mean of m + 3, m + 5, m + 6, m + 9 and m + 12 is:

Correct option is C

Given:

The numbers are: m + 3, m + 5, m + 6, m + 9, m + 12

Formula Used:

Mean = ​$$\frac{\text{Sum of all terms}}{\text{Number of terms}}$$​​

Solution:

Sum = m + 3 + m + 5 + m + 6 + m + 9 + m + 12 = 5m +35

Mean =$$\frac{5m + 35}{5} = m + 7$$​
