Question

Need help with the blank ones

Answer 1

Explanation:

4 6 10 18 34 66 130 n^2+2

1 4 9 16 25 36 49 n^2

2 4 8 16 32 64 128 2^n

2 6 12 20 30 42 56 n^2+n

this is Fibonacci, 1 1 2 3 5 8 13 21, and its hard to come up with a rule because you need to know the number one before and two before and add them together.
