Correct Answer - Option 4 : None of the above
Concept:
The mean of a set of numbers is the sum divided by the number of terms.
mean = \(\rm \frac{sum \: of\: the \: terms}{number\: of \:terms}\)
Calculation:
Given the numbers are 4, 6, x, 10, 12, 16
mean is 14
\(\rm 14 = \frac{4 + 6 + x + 10 + 12 + 16 }{6} \)
84 = 48 + x
x = 84 - 48
x = 36
∴ The value of x is 36
