1. The rest of the sequence may or may not have infinite EVEN integers

Hence insufficient.

2. The sequence could also have infinite EVEN integers as well. Infinite + Infinite would still be Infinite.

Hence insufficient.

Combining both doesn't give us any added information hence the answer E

I agree that the answer is E.

Alpha Sequence: Infinite odds, Finite evens

(1) Doesn't mention anything about odds
(2) Doesn't mention anything about evens

(1 and 2) You know that there are infinite odds, but you don't know whether there are infinite evens or not (all you know is that the first 10 integers are even, but that doesn't mean that there aren't any more).

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
