It's yrsvjrt
Explanation: it's the word "teacher", typed one key to the right. If you go one key to the left back again in the word teacher it gets obvious.

I guess I'll post one.

1, 6, 18, 40, 75...

I at least think this one will be hard to crack...

1112213211 x

Well I did only ask for the next line which is quite correct but since you have continued the third line is wrong it should be

1113213211 and therefore the fourth line should be

31131211131221 but you have obviously worked out the sequence congratulations. When this was put in front of a group of computer graduates it took the brightest of them a week to work it out.

What's next?

34

That's called the fibonnoci sequence. You put two ones and then add them up, which equals 2. Then you add the one and the 2 up to get three. you keep repeating the pattern

I don't think it's exactly right but I think it's close.

Methinks it's 500 400 900 800 1300 1200 1700
Is that the answer?

Off the top of my head, and what I can remember about certain people being into Math, I can only think of three members who may have got this one: Bear, Mette and Patrick (MS)... and me, of course.

Who the heck does then.

Here's a warm up for Toon Dog's.

It isn't too easy but it isn't as hard as my last one.
1, 2, 0, 4, -4, 12, -20...
Find the next 3.

PS: Toon Dog, don't get too angry if nobody can solve it. The way I think is I find a rule for a pattern by manipulating variables according to position and previous terms. If that fails, I look for a pattern, and if THAT fails, I give up. I'm on step 2 (find a pattern) for yours. All of mine can be solved by manipulating background values and using them to change the answer.

EDIT: Fixed a bug in my pattern
