How to print last element of sub array in a 2d array ruby

Question

I'm new to ruby and i want to print the last element in a sub array from a 2d array. I've tried using an each iterator but it gave me an error: "no implicit conversion of Array into Integer (TypeError)"

pairs = [['name', 'sam'], ['age', '56'], ['height', '179']]

pairs.each{ |x| puts pairs[x][1] }

Preferred output:
sam
56
179

Any suggestions will be appreciated! Thanks.

Within the each block, x refers to a single sub-array at a time, e.g. for the first iteration you can think of x = ['name', 'sam']. Does that help? — Stefan

You are almost there pairs.each { |x| puts x[1] }
