Try this...

C1: =RAND()
C2: =IF(MOD(ROW(),2),RAND(),C1)

Copy the formula in C2 down as far as needed.

I want to use the rand() function to put the same random value in two
adjacent cells in a row and then a new random value in the next two cells,
etc. The appearance might typically look as follows: c1=.33784,
c2=.33784,
c3=.11562, c4=.11562, c5=.01356, c6=.01356, c7=.88158, c8=.88158, etc up
to
about cell c2000.
