6. 2 4 8 10 20 22 _ _ 92 94

The pattern appears to be alternating operations: multiply by 2, then add 2.
2 * 2 = 4
4 + 2 = 6 (This does not match the given 8)
Let's re-examine:
2 * 2 = 4
4 * 2 = 8
8 + 2 = 10
10 * 2 = 20
20 + 2 = 22
The pattern is: multiply by 2, add 2.
The missing numbers are: 22 * 2 = 44, and 44 + 2 = 46.
The sequence continues with 92 and 94, which do not fit this pattern.
The question is incomplete or requires external knowledge.
