find the numbers
2493 ----- ------ ----- ----- 8008
could be
2493 3596 4699 5802 6905 8008
or
2493 3148.347 3975.969 5021.152 6341.087 8008
hard to tell without further information.
For my first one, I assumed the number were in an arithmetic sequence, for the second answer I assumed a geometric sequence.
