Find Non Blank Calls

I need to create a formula that counts the number of blank cells to the right and then actually uses the value in the non blank cell.

The result requiired is that the formula will find the difference between 1 value, the next non blank cell and then will average the cells between to get the interval figures.

eg. Value1 is 50.
Value2(the next nonblank) is 60.
There are 4 empty cells in between.

I need a formula that will find the next Nonblank (Value2), calculate the difference between Value1 and Value2, then divide that by the number of blank cells + 1 and add the value to the left.

The cell in A2, calculated manually at the moment would be:
=A1+((A6-A1)/(4+1))
This would then be altered across the page so that A3 would be:
=A2+((A6-A2)/(3+1)

etc., etc.

Therefore the result returned across the blank cells would be:

A1 A2 A3 A4 A5 A6
Value1 BLANK BLANK BLANK BLANK Value2
50 52 54 56 58 60
