- increase 2 then decrease 2 after that double the num
repeat process. Ans: 14. - 12 years agoHelpfull: Yes(10) No(0)
- ans 18
three series
4,8,16
2,6,18
4,8,16
- 12 years agoHelpfull: Yes(7) No(11)
- ans:14
4-2=2
2+2=4
4*2=8
8-2=6
6+2=8
8*2=16
16-2=14 - 12 years agoHelpfull: Yes(4) No(0)
- series is 4,8,16------1st
2,6,14------2nd
4,8,16 --------3rd
2+4=6,6+8=14
so ans is 14 - 11 years agoHelpfull: Yes(3) No(1)
- according to my logic.. this is mix series
start 1st series with 4
then left 2 n 4 move to 4th digit 8 in same sequence
4*2=8, 8*2= 16 and so on..
for next series
start with 2 4_6 8_10 12_... and so on
so the ans should be 10 - 12 years agoHelpfull: Yes(1) No(5)
- add corner term=4+4=8 it is next series first term
add middle term form next term 2+4=6 similary
8+8=16
8+6=14 which is the ans
- 11 years agoHelpfull: Yes(1) No(0)
