The pairs of numbers seem to follow a specific pattern. Let's analyze the sequence you provided:

2,3 → 1,4 → 2,7 → 10,12 → 1,3 → 2,5 → 3,10 → 4,5 → 7,9 → 7,13 → 1,2

First, let's break it down:

• The first pair is (2,3).
• The second pair is (1,4), and so on.

This sequence does not immediately appear to follow a simple arithmetic or geometric pattern, but there may be another rule or relation underlying the pairs.

I will look into possible relationships between these pairs of numbers such as sums, differences, or positions in the sequence. However, more clarification on the sequence's rule may be needed to provide a precise answer.

Would you like me to continue exploring possible relationships, or do you have more information about the sequence?
