Arithmetic Progression

I am trying to figure out the missing pay range (min, mid, max) below. I do not know if the job level number has any correlation to anything, but included it anyway.

Job Level Min Mid Max
90 ? ? ?
104 ? ? ?
120 4504 5630 6756
138 5069 6336 7603

This response is numbering the rows 0 onwards.
If we notice carefully, there is a correlation among successive 'Job Level' entries.

JL0 = 90
JL1 = 104
JL2 = 120
JL3 = 138

Let us compute the difference between these successive entries and label the difference as d0, d1, d2 respectively.

d0 = JL1 - JL0 = 104 - 90 = 14
d1 = JL2 - JL1 = 120 - 104 = 16 = d0 + 1*2
d2 = JL3 - JL2 = 138 - 120 = 18 = d0 + ...

Solution Summary

There is a correlation among successive entries in each column; solution explains that in detail.
