Some stickers are in a packet.
If Adam puts them into groups of 9, there are 2 stickers short.
If Adam puts them into groups of 7, there are 5 stickers short.
Find the smallest possible number of stickers in a packet.
Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81
Multiples of 9 (-2): 7, 16, 25, 34, 43, 52, 61, 70, 79
Multiples of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84
Multiples of 7 (-5): 2, 9, 16, 23, 30, 37, 44, 51, 58, 65, 72, 79
