by Alan Fetters

First, solve the cross differences puzzle according to the directions. The result is:

The entries clued by a ‘?‘ are as follows:

258961   = 1  -> A
8291     = 14 -> N
92847    = 18 -> R
837192   = 18 -> R
26715    = 7  -> G
82769    = 16 -> P
659423   = 5  -> E
95817    = 18 -> R
14796    = 1  -> A
932741   = 4  -> D
24953    = 5  -> E

The letters indexed by the number anagram uniquely into one word, the answer: PREARRANGED.
