6=3x2
30=5x6
210=7x30
next number, (say A)= 9x210
still next B= 11xA

The pattern appears to be the multiplication of prime numbers. The next number in the sequence is:
1*2*3*5*7*11 = 2310

Multiply by Prime numbers
1 X 2 = 2
2 X 3 = 6
6 X 5 = 30
30 X 7 = 210
210 X 11 = _______

It is multiplying by consecutive prime numbers.
The prime numbers (numbers who's factors are only 1 and themselves) in order are: 2, 3 ,5, 7, 11, 13, 17...
1*2 = 2
2*3 = 6
6*5 = 30
30*7 = 210
210*11 = 2310
2310*13 = 30030
The next two numbers are 2310 and 30030

Consider the series of prime integers: 1, 2, 3, 5, 7, 11, 13, ...
The value of the nth item is the product of the first 'n' items in the "prime number" series.
So the next 2 numbers would be 2310 and 30030.

the solution is 210, 1890, 20,790
'you increase multiplication by two each time 2x3=6 6x5=30 etc
