Can anyone explain the Fibonacci sequence, I understand that the third term is suppose to be the sum of the two previous numbers, but this is becoming confusing.

The first four terms in a pattern are 4, 7, 10, and 13. What is the fifth term in the pattern?

Shouldn't it be; 4,7,11,18?

f1 = 4
f2 = 7

f3 = f2 + f1

f4 = f3 + f2

f5 = f4 + f3

your pattern is not fibby, why are you wanting to make it a fibby?

Ohh, because, I was learning about it in the section. It never occurred to me that it wouldn't be. . .

it looks arithmetic to me ....

writing out the difference tiers tends to be useful to me when trying to find a pattern

4  7   10   13
  3  3     3        looks to be adding 3 each time

Okay, I see the pattern now that I've stopped applying the Fibonacci technique, thanks.
