a have a table

x=1,2,3

y=1,8,27

i need to find what the 6th number for y.

How do i do it?

Note that the y values are cubes:

y₁ = 1 = 1³

y₂ = 8 = 2³

y₃ = 27 = 3³

The general rule is y = x³

The x values are an arithmetic series with a starting value of 1 and incremental value of 1, so

x₆ = 6

y₆ = 6³ = 216
