The number in this sequence increase by 3 each time.?
2, 5, 8, 11, 14
The sequence continues in the same way. Will the number 333 be in the sequence? Yes or no? Explain how you know.

answers:
TomV say: If 333 is in the sequence then 333 = 2+3n with integer n.
333 = 2 + 3n
331 = 3n
n = 331/3 ≠ integer
Ans: 333 is not in the sequence
=======================
a_n = 2 + 3n
a_110 = 2 + 330 = 332
a_111 = 2 + 333 = 335
Ans: 333 is not in the sequence because the sequence jumps from 332 to 335 skipping 333 and 334
===========================

David say: No, 333 is not in the sequence because the nth term is 3n -1
-
rotchm say: Note that ur sequence is always 2 more than a multiple of 3.
Is 333 two more than a multiple of 3?
