(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] expressions of integers

1. The problem statement, all variables and given/known data

Let n be a positive integer. How many ways can you express a as the sum of positive integers? Order of addition does not matter.

EDIT: change "a" to "n" in the second sentence

2. Relevant equations

3. The attempt at a solution

Let f(x) be the function that gives the number of ways you can express x as the sum of positive integers? Order of addition does not matter.

f(1)=1

f(2)=2

f(3)=3

f(4)=5

f(5)=7

I do not see the pattern. I was hoping for Fibonacci numbers...
