How did i get it?

It’s quite simple, when ever you see questions like this, try to find if the numbers have linear or exponential relation. If it is non of them, then always try to make a relation between differences. For example, here differences are:

4 - 3 = 1

8 - 4 = 4

17 - 8 = 9

33 - 17 = 16

Now, if you observe differences carefully then you may found that differences are in a chain,

1 = 1^2

4 = 2^2

9 = 3^2

16 = 4^2

So,

4 = 3 + 1^2

8 = 4 + 2^2

17 = 8 + 3^2

33 = 17 + 4^2

Now, if next number is x then,

x = 33 + 5^2 = 58.
