[12]

gv a few more no.s [3]

well is it correct ?

or u made some typo ?

hey i am damn sure... u missed a term...

it shud be : 2, 5 , 12, 31, 86 , so on...

becoz...

2 = 3⁰ + 1

5 = 3¹ + 2

12 = 3² +3

31 = 3³ +4

86 = 3⁴ + 5

.

.

so one is GP. and the other AP.

basic assumption while solving question must be : The question is 100% correct and the question setter has a perfectly sounding mind... [3] [4]

well sky... may be the question is wrong or may be u r limiting ur analysis as u feel d question is wrong... so think once again, there may be another such relation possible that forms the given sequence... [1]

well, i gave a thought over it yesterday n concluded that i can't conclude anything... [2] [6]

huh!

Y PPL GIVE QUESTIONS ???

dear kishan, have u forgotten dat u had given this one once ??

Hey Sky, now that you had started, why not find out the 10 terms and add them manually.[3]

It's an AGP and there is a standard method to solve these questions............[2] Thing is I forgot it. [2]

arey wat to remembre...

(kuchh yaad rakhne ka hota... toh main bhi bhool hi jati [3]
par yaad rakhne ka toh kuchh hai nahi... isiliye mereko yaad hai [3])

take it separately as an AP and another GP..

bus add.. upto 10 terms..

bus [3]

6560 is the answer then [4]
