Hi Experts,
I eliminated the second statement due to the following reason:
The second-to-last term is 3^10. So, the last one should be 3^11.
But the catch is that, the target question does not provide any information about the elements of the sequence being -ve, +ve, integer of fraction. So, we fail to determine the very first term of the sequence. Consequently we cannot decide the fourth term as well. INSUFFICIENT
The reason provided by Manhattan:
(2) INSUFFICIENT: We can use this information to find the last term and previous terms, however, we don't know how many terms there are between the second-to-last term and the fourth term.
I have hard time grasping the concept, especially the underlined portion. Could you please tell me if there is anything wrong in my reasoning? Also, what exactly does manhattan reasoning mean?
