It say set 12: subtracting 2; differences of 2. A triangle has a 3 on top and a 2 on the left bottom?
Based on the information you provided, it seems like you're referring to a triangular number sequence. In this particular case, the sequence starts with 12 and each subsequent number is obtained by subtracting 2 from the previous number.
To find the other numbers in the sequence, you can continue subtracting 2 from the preceding number. Here's an example:
1st number: 12
2nd number: 12 - 2 = 10
3rd number: 10 - 2 = 8
4th number: 8 - 2 = 6
Regarding the triangle you mentioned, it sounds like you are describing a number triangle where there is a number 3 at the top and a number 2 at the bottom left. This type of triangle often represents a pattern where each number is the sum of the two numbers above it. However, based on the information you provided, it's not clear how the triangle and the number sequence are related. Could you please clarify?
