Question
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?

Answer
Note that the y values are cubes:
y₁ = 1 = 1
y₂ = 8 = 2
y₃ = 27 = 3
The general rule is y = x

The x values are an arithmetic series with a starting value of 1 and incremental value of 1, so
x₆ = 6
y₆ = 6 = 216
