given series: 8 2 14 6 11 ? 14 6 18 12
odd term series: 8 14 11 14 18
even term series: 2 6 x 6 12
odd term series:
8+(6)=14
14+(-3)=11
11+(3)=14
14+(4)=18...where +6,-3,+3,+4 is the series of common difference b/w adjacent numbers in
odd term series. now +4, +3, -3, +6 would be the series of common difference b/w adjacent numbers in even term series.
So,even term series:
2+(4)=6
6+(3)=x
x+(-3)=6
6+(6)=12---->x=9.....So, value of x =?=9....

difference between (8,2)=6 decreasing
(2,14)=12 increase
(14,6)=8 decrease
(6,11)=5 increase
and from right to left
(12,18)=6 increase
(18,6)=12 decrease
(6,14)=8 increase
so they just reversing the order and order of decrease and increase
so we have to deduct from 1
hence ans is 9

ans is 9 beacuse 8-2=6,14-2=12,14-6=8,11-6=5this is from left to right from right to left this reverse so 5 is added to 6 in left to right to get 11 and similar;y 5 should be decreased from 14 from right tot left so 14-5=9
