6*11=66,89*101=8989,706*1001=706706. next two sequence are?

The solution would be like this for this specific problem:

2nd factor product goes like this: 11, 101, 1001, so the next 2nd factor would be 10001.

1st factor can be solved thru using a polynomial function.

(n) = 267n² - 718n + 457

FirstFactor (4) = 1857

So, the 4th product is 1857 * 10001 = 18571857
