There is a relation between rectilinear-adjacent squares such that there is a unique rectilinear path from the top-left corner of the grid down to the bottom-right corner of the grid. Each square can participate in the path only once. What is the relation and the path it induces?

I believe
Every pair of numbers have no common factors (other than 1). So they are co-prime. Hopefully I haven't made a mistake...
