my answer is A

Raising Sun I accept D is subjunctive... can you explain what is the problem with C?. why should we reject it?

i would go for A... what is the OA?

I picked C... can anybody explain what is the problem with option c?. is parallelism the reason for making A as the choice or is there any other reason?

B sounds better

thanks a lot for your explanation genius in the gene..... But just got to clear something from you... U told from statement 1 we know that y is positive... so y should be 5. question asks that y = 5?. so this answers the question right?... or where am i going wrong?..

Jen1984 I just did the same mistake you did. the question is 2^{(4-1)^2}/2^(3-2). ...so it cant be 2^5.. ...trying to get over "Misplaced Bracket" syndrome...

sorry about that just created the thread in a hurry

no .. the OA is not C... it seems to be D... i dont know how it is... e.cartman and 12rk34 please explain

yeah... sorry for missing the brackets...

For every integer k from 1 to 10 , the kth term of a certain sequence is given by (-1)^(k+1)*(1/2^k). If T is the sum of the first 10 terms in the sequnce. then T is a.greater than 2 b.greater than 1 and 2 c.greater than 1/2 and 1 d.greater than 1/4 and 1/2 e.less than 1/4 please explain the approach in detail....

2^(4-1)^2/2^3-2 a. 2^8 b. 2^7 c. 2^6 d. 2^5 e. 2^4 This problem seems to be easier. But i am getting it wrong again and again . somebody please explain .... OA later..

thanks a lot.. got it

e.cartman please explain what are the points you considerd for finding the slope. I am stuck with 1/2 as my answer.............

john why are you considering distance from the origin as the height of the traingle? please explain...
