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