Linear array + scale array

Hi everyone,

I'm trying to do a linear array where the space between each elements is increasing linearly.

Let's say I got 5 cubes in a line, space between the first two cubes is 1, space between the second and third is 1.5, space between the third one and fourth is 2... and so on.

I also want to do this kind of effect where the array is linear but the size change based on where the point is in the array.

Btw it was done in Vectoraster on Osx.
