What is the next number of the following sequence
6, 3, 3, 9, 12, 5, 7, 35, 8, 6, 2,?
Read Solution (Total 6)
-
- Look upon the series carefully
6, 3, 3, 9, 12, 5, 7, 35, 8, 6, 2,?
6 - 3 = 3
3 * 3 = 9
12- 5 = 7
7 *5 = 35
8 - 2 = 6
6 * 2 = 12
so answer will be 12

- ANS 12
Logic :
take 4 terms :
sum of middle terms is first term and multiplication of middle term is last term
(6, 3, 3, 9) = (6=3+3), (3*3=9)
(12, 5, 7, 35) = (12=5+7), (5*7=35)
(8, 6, 2, ?) = (8=6+2), (6*2=12). - 10 years agoHelpfull: Yes(5) No(0)
- 6,3,3,9
so next terms
6-3=3
3*3=9
similarly
12,5,7,35
next term
12-5=7
5*7=35
so 8,6,2,12
8-6=2
6*2=12
so ans is 12 - 10 years agoHelpfull: Yes(1) No(2)
- 6-3=3 3*3=9
12-5 7 7*5=35
8-6=2 2*6=12
- 10 years agoHelpfull: Yes(0) No(0)
- 6-3(2nd possition)=3(3rd possition)
3(3rd position)*3(2nd position)=9
12-5=7
7*5=35
8-6=2
2*6=12(ans) - 10 years agoHelpfull: Yes(0) No(0)
- 3+3=6
3*3=9
5+7=12
5*7=35
6+2=8
6*2=12 - 10 years agoHelpfull: Yes(0) No(0)
