Number sequences

THE goal of this game is to figure out the number pattern
For instance
1 1 2 3 5 8 13
The answer would be add the 2 numbers together to get the next
Try to give atleast 5 numbers

Begin

3 6 30 870 756030

 

Easy, x*(x-1) with a starting value of 3.
3*2 = 6, 6*5 = 30, 30 * 29 = 870 & 870*869 = 756030.

Next: 2, 8, 18, 50, 98, 242, 338

 

Should have known matryoshika was a math nut

I came up with( x)^2-X
For mine i cant figure out yours becidez there all multiples of 2

 

Thanx

 

Mine: 1 8 77 834 2125 2345 5892 8192

 

You need to solve previous instance

 

You know that 1 isnt a prime number right?

But anyway:

2 = 2 * (1^2)
8 = 2* (2^2)
18 = 2*(3^3)
50 = 2*(5^2)
98 = 2*(7^2)
242 = 2*(11^2)
338 = 2*(13^2)


next one would be 578 = 2*(17^2)
