If we assume that 2nd digit is x.
Then,
1st digit would be x^2
2nd would be x
3rd would be 10 - x
4th would be x + 1
5th would be 4 + x
Now,
the sum of all digit is 30
means,
x^2 + x + 10 - x + x + 1 + 4 + x = 30
Then,
x^2 + 2x + 15 = 30
x^2 + 2x = 30 - 15
x^2 + 2x = 15
x^2 + 2x - 15 = 0
x^2 + 5x - 3x -15 = 0
x(x+5) -3(x+5) = 0
(x-3) (x+5) = 0
x = 3 and x = -5
But negative number is not considered.
so, x=3
That forms following PIN
Pin is 93747
Then,
1st digit would be x^2
2nd would be x
3rd would be 10 - x
4th would be x + 1
5th would be 4 + x
Now,
the sum of all digit is 30
means,
x^2 + x + 10 - x + x + 1 + 4 + x = 30
Then,
x^2 + 2x + 15 = 30
x^2 + 2x = 30 - 15
x^2 + 2x = 15
x^2 + 2x - 15 = 0
x^2 + 5x - 3x -15 = 0
x(x+5) -3(x+5) = 0
(x-3) (x+5) = 0
x = 3 and x = -5
But negative number is not considered.
so, x=3
That forms following PIN
