Okay, here's one:

2, 7, 20, 54, 148, ...

2, 7, 20, 54, 148
5,13,34,94 (difference between sequential numbers)
13/5 = 2.6
34/13 = 2.615
94/34 = 2.76
94*2.6=244.40
5,13,34,94,244
Sequence approximate: 2,7,20,54,148, 392

No pattern sequentially.

2+7+(11) = 20 <---throw to pattern. First number in sequence should be 3, not 2. Thus 3+7+(10)= 20.
7+20+(27)=54 Fits pattern.
20+54+(74)=148 Fits pattern.
54+148+(202)= 404 Fits pattern.

The answer is 404 if you correct your pattern and change the first number to 3.

404 eh? Not found? Was this a deliberate trick? :xD:

404 is close...the next number is 403. I was using:

a_n = floor(e^n)

Each number in the sequence maps to the number of letters it takes to spell (in English) the corresponding natural number. Thus the 11th term in the sequence is the number of letters in "eleven" which is 6.
