Please help me with an Odd Number Out puzzle. I know it's not a crossword but I am pulling my hair out....and I don't have much left!
The question asks:
Which is the odd number out?
6472, 3297, 9782, 3964, 8342.
As it's a brain teaser, I doubt that it is so simple to be 3297 because it ends in an odd number...or in fact is an odd number.
Is there something glaringly obvious that I am missing?
Please help before I go bald!
