The mean of five positive integers is 1.5 times their median. Four of the integers are 8,
18, 36 and 62, and the largest integer is not 62. What is the largest integer?

Four of the five integers are:  8, 18, 36, and 62.

Since the largest integer is not 62, the fifth number must be larger than 62.

The median is 36.

The mean is 1.5 times the median, or 54.

  54  =  (8 + 18 + 36 + 62 + x) / 5

  54  =  (124 + x) / 5

270  =  124 + x

    x  =  146
