The successive differences in the values are 1 2 4 8 16 32, i.e., powers of 2. Also, the y values are one less than the corresponding power of 2 produces by the x value.

So y = 2^x - 1

y = 2^x - 1

when x = 0, y = 2^0 -1 =0
x = 1, y = 2^1 -1 =1

x is an arithmetical progression and y is a geometric progression. So, work out the formula for y.
