Determine the pattern: What comes next?

.1, 1, 2, 4, 7, _

.4, 9, 16, 25,_

Explain. I need help explaining. Thank you.

First looks like a sort of Fibonacci sequence, where each term is the sum of the three previous terms, making the sequence
1,1,2,4,7,13,24,44,...

However, that assumes a leading term of zero.

The leading .1 throws me off.

Or, it could be that each term is one less than a Fibonacci number:
Fib: 1 2 3 5 8 13 21 34 ...
You: 1 1 2 4 7 12 20 33 ...

The second one is obviously a sequence of perfect squares. Next is 36.
