What is the pattern to this sequence?
1,3,4,7,11,18,29
I figured it was plus the last 2 numbers which will then equal the next number. But I got messed up and can't figure the next 3 numbers in this pattern, any help is helpful.
THanks

You're right.
1 + 3 = 4
3 + 4 = 7
4 + 7 = 11
7 + 11 = 18
11 + 18 = 29
18 + 29 = ?
