Two numbers are missing in this pattern:

2, 4, 11, 37, 153, ??, ???

What are they?

We begin with 2, and then follow the given operations to arrive at the desired result:

2 * 1 + 2 = 4

4 * 2 + 3 = 11

11 * 3 + 4 = 37

37 * 4 + 5 = 153

153 * 5 + 6 = 771

771 * 6 + 7 = 4663

Thus the two numbers are: 771 and 4663.
