Take any number in the sequence
2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35, 38, 41, 44, 47, 50, 53, 56, 59, 62, 65, 68, 71, 74, 77, 80, 83, 86, 89, 92, 95, 98, 101, 104, 107, 110, 113, 116, 119, 122, 125, 128, 131, 134, 137, 140, 143, 146, 149, 152, 155, 158, 161, 164, 167, 170, 173, 176, 179, ...
and investigate which multiples of that number are in the sequence. Is the result true for all members of the sequence? Prove any result you find.
My answers:
2 gives 2, 8, 14, 20, 26,...
5 gives 5, 20, 35, 50, 65, 80,...
8 gives 8, 32, 56, 80, 104, 128, ...
11 gives 11, 44, 77, 110, 143, 176, ...
It looks as if the any number in the sequence has multiples of that number. Any clever one of you could tell me how to prove this as I am stuck please![Frown :frown: :frown:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
