Well, from the first three terms, we can tell that this is a geometric sequence with an r value of 3.

This is because 2 * 3 = 6, 6 * 3 = 18

We can just continue this until we reach 486

So we do 18 * 3 = 54

54 * 3 = 162

And just to make sure that there are no more,

162 * 3 = 486

So the missing terms are 54 and 162
