chetan2u , Just for your information that nobody is there to respond in GRE sub-forum or the GRE prep club. I have checked myself. So, I request you to pls allow GRE students to post their queries here itself till the time they won’t get any help from the Gre Sub-forum. So that they won’t get lost. Please consider my request.

I am really confused here, isn’t both 2 & 6 are the correct answer ?

Rangerwarrior , you don’t require to solve the equation to get the answer. On right side you have a square root,which cannot be NEGATIVE. So, left side also cannot be negative. But x as 2 gives 2-5 or -3. Similarly from x-5 >=0 means x can be 5 or 6. x as 5 will give 0 on the left side but the right side will not be 0(you can check the unts digit only). Answer x=6 poojaarora1818 , sure put your question here as we are here to help you all. But do post it in the new chat opened for the purpose. It will become active only when we start shifting our questions there. mchat.php?room_id=50050793

chetan2u , Thank you for your positive response. But let me tell you that I am not a GRE student. I am a Gmat student. I am doing this because I can understand the pain of a student who really struggles when they seek replies for their respective quieries. That’s it. Thank you!

Howdy folks! Hope everyone’s prep is going fine I wanted to know if there’s a more efficient way of solving below without listing all the terms (TIA!): Sn is a sequence such that it’s nth term is sum of first npositive integers. Tn is a sequence such that its first 2 terms are 1 and starting from the 3rd term, each term is the sum of the previous 2 terms. HOw many numbers less than 100 belong to both Sn and Tn ? If this question is already discussed somewhere can someone share link pls ? I searched online but found questions where first 3 terms or 6th/nth term is asked..

poojaarora1818 , it is good to see you thinking of other students too.

Could you please post entire question with the OA and the options exactly as seen in the original source? Also, could you please tell the source? Thank you!

I don’t think there would be a better approach. Even if there’s, that would be complicated and time consuming. Below 100, there is 14 terms in series Tn. So relatively easy
