Find ‘x’

How this game works is that I give a string of numbers with an unknown pattern. Your goal is to figure out that pattern and find what x equals.
Anyone is welcome to post a question.
The first question is this:
0, 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, x
What is x?

Now, this one is harder.

What is x?

(Hint: look at the previous question)

Let’s try something easier. So it can be fun for those who don’t want to spend too much time on it.

1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, x

The numbers never go down. The multiplier between the numbers are:

2, 1, 2, 2, 4, 8

I don’t know if this is in the right direction, but it might help someone else who tries to crack this.
