It took me a couple tries with the search engine, but I found an old post by geoschmo that gave the progressions:

For a Low Tech Cost Game:
The multiplier is simply tech level. It is linear.
For Example, Ship construction
Level Cost = 10000
Level 2 cost is 10000 X 2 = 20000
Level 3 cost is 10000 X 3 = 30000
Level 4 cost is 10000 X 4 = 40000
For a Med Tech Game:
The multiplier is the result of Tech Level rasied to the power of 2 and then divided by 2.
For example, Ship Construction again
Level 2 cost is 10000 X 2(2 to the power of 2 is four divided by 2 is 2) = 20000
Level 3 cost is 10000 X 4.5(3 to the power of 2 is 9 divided by 2 is 4.5) = 45000
Level 4 cost is 10000 X 8(4 to the power of 2 is 16 divided by 2 is 8) = 80000
For a High Tech cost game the multiplier is
Tech level raised to the power of 2
Ship Construction again
Level 2 cost is 10000 X 4(2 to the power of 2 is 4) = 40000
Level 3 cost is 10000 X 9(3 to the power of 2 is 9) = 90000
Level 4 cost is 10000 X 16(4 to the power of 2 is 16) = 160000

Cap'n Q
The most merciful thing in the world, I think, is the inability of the
human mind to correlate all of its contents. We live on a placid
island of ignorance in the midst of black seas of infinity, and it was
not meant that we should go far. -- HP Lovecraft, "The Call of Cthulhu"
