In Ruby, you can obtain the mean (average) of an array of numbers by using the sum method combined with the size method. Here’s a simple example:

numbers = [1, 2, 3, 4, 5]
mean = numbers.sum.to_f / numbers.size

This code calculates the sum of the elements in the numbers array, converts it to a float for accurate division, and divides it by the number of elements to get the mean.
