5=17
1=5 (1*3)+2
2=7 (2*3)+1
3=9 (3*3)+0
4=13 (4*3)+1
5=17 (5*3)+2 |

This doesn't make any sense to me.
Mine is
1=5
2=5+2^1=7
3=5+2^2=9
4=5+2^3=13
5=5+2^4=21 |

Just saw yours, nice, I couldn't find another better one, so I guess it is the right answer? |

5+2^0 would give 6 though... so 5+2^(n-1) doesn't fit perfectly either, but I can't come up with anything better.
Fortunately I think it has been proven that any number can be a logical continuation of any number sequence, which makes any answer a correct one :p |

My high school math teacher told me: given any 3 numbers in the world, he can find the 4th one to fit perfectly with an equation that calculated from the 3 numbers. |

The OP wasn't asking for a number sequence. If he had, my answer would be wrong. All he wanted was the pattern of the five numbers and I gave him one. For my answer it is (n*3) but then you add a number. Look at the order the numbers go. -2, -1, 0, 1, 2. That's the pattern.
Since the OP has since changed the topic that would lead me to believe I am right. |

Your answer is fine, just like many others. Just write it as n*3+|n-3| and it's even more consistent than the other suggestions. |
