Observe this series of number:
1, 4, 9, 16, 25, 36, 49
Do you see a pattern or a sequence? If you don't, it's okay. And this is what I learnt today. It takes time and practice for my eye to catch the patterns. I have to look at it carefully and think, what is it that makes the numbers get bigger. Once you get the pattern, you will find yourself extending the pattern or looking for other different patterns to work with.
The number nine is interesting to work with in terms of patterns.
Let's take a look at some patterns...
21 - 12 = 9 (9 x 1)
31 - 13 = 18 (9 x 2) The number 2 came about by subtracting 1 from 3
41- 14 = 27 (9 x 3) Following pattern, number 3 came about by subtracting 1 from 4
Therefore 91-19 = (9 x 8) = 72

After analyzing patterns involving the number nine, naturally i wanted to look for other kinds of patterns using other digits. Below attached is a video that i found online involving the number 6 and 4, using 5 point star method.
