| Let the second number be x, then the first 1.5 * x. To find the arithmetic mean, you need to add the numbers and divide by their number.
(x + 1.5x) / 2 = 37
2.5x = 37 * 2
2.5 * x = 7.4
x = 74 / 2.5
x = 29.6
So the second number was 29.6, and the first:
29.6 * 1.5 = 44.4.
Answer: These numbers are 44.4 and 29.6.
