1 5 10 17 26 the law of these numbers

These numbers are squares plus one
That is: 0 + 1, 4 + 1, 9 + 1, 16 + 1, 25 + 1
After subtracting 1 from each number in the sequence, it becomes:
0、4、9、16、25
They are the squares of 0, 2, 3, 4 and 5
If the first number is 2, not 1, then the law is more obvious
It's the square of 1, 2, 3, 4, 5 plus 1
