Answer 2

@dan815 @paki @Ashleyisakitty

Answer 3

is it D?

Answer 4

Hate, hate, hate, HATE these problems. There are infinitely many answers.

3760, 1880, 360, 180, 45, ?

Try dividing successive pairs...

3760/1880 = 2
1880/360 = 5 2/9
360/180 = 2
180/45 = 4

That doesn't seem to be getting us anywhere.

Try subtracting successive values...

3760 - 1880 = 1880
1880 - 360 = 1520
360 - 180 = 180
180 - 45 = 135

That doesn't look very helpful, either. Just play around until you find something,

Answer 5

ahhhhhhhhhhhh

Answer 6

some say that it's D coz 45/2=22.5 but that doesnt make sense

Answer 7

Not every sequence males a ton of sense. You just have to find something. Seriously, though, you can put ANY number next and it can be explained.

Answer 8

lol it's from a university entry test so u can't put any no. coz every que matters in that and u can't risk losing a mark

Answer 9

read it like this :

3760 --> 1880
360 ---> 180
45 ----> ?

Answer 10

then it'll be 22.5...that makes sense @ganeshie8

Answer 11

thanx

Answer 12

That's one way to look at it - simply ignore any connection between 1880 and 360. This might be described as an overlapping pair of sequences.

Answer 13

the first terms are coming from nowhere, but the second terms are generated by dividiing...

again there are plenty of mistakes in this post. few are below :
1) its a sequence, not series
2) you cant describe a sequence just by listing first few terms

Answer 14

its an iq que from last year past paper for entry test...i was preparing and couldn't figure it out so i posted it here as it is @ganeshie8

Answer 15

its okay, the question as it stands is not mathematically meaningful. but yeah your brain somehow manages to see the intent of the author of question

Answer 16

yea

Answer 17

@ganeshie8 care for confirming my ans for some other iq ques?

Answer 18

il try.. ask

Answer 19

"your brain somehow manages to see the intent of the author of question"

No, that just isn't the case. Maybe, with some great stroke of luck, you might manage to trip over the intent of the author. You can't know it. Even if you find it, you can't claim any directed path to the solution.
