How did you get that answer?
I look for some kind of pattern
I noticed that the differences between the second set of numbers were consecutive odd numbers.
Past experience told me that involved some type of squaring
I then noticed that each number in the second set was 2 more than a perfect squares, which are 1,4,9,16, 25 etc
That is about the best way I can explain it.
You just have to try different patterns
