using differences to identify patterns
7;22;43;70;103;
2,36,81,144,2
What is the distinction between the numbers separated by semicolons and the numbers separated by commas?
Is the last number really 2?
In the first series, the difference between numbers keeps increasing by 6. The next number should be 103 + 39 = 142
The last series makes more sense as
9,36,81,144,225
(3^2, 6^2, 9^2, 12^2, 15^2)
