Re: find the number

Here is my answer....

Next number in this series is 24,78.

Logic:

1,3,,5 th terms incrase the number 4,6,...
2,4,6 th terms increase the number 12,18,....

Is there any problem for this logic?

Re: find the number

Ohhh now i got why the number 8 will come there....

Mutiply the intial number by 3 and then divide the next number by 2.

Re: find the number

thats what iam telling suresh

your ans should be 26(and not 24)!If i go with your formula


see


12-8= 4

18-12=6

so the next term should be 18+8 and not 18+6

r u getting me?


bye
