-
- I think its A 14
(-2, +2,*2) is the pattern I can see - 8 years agoHelpfull: Yes(62) No(0)
- (4,8,16)
(2,6,18)
(4,8,16)
series is 4,2,4,8,6,8,16,18,16
so option will be (d) - 8 years agoHelpfull: Yes(17) No(13)
- 4-2=2,2+2=4,4*2=8,8-2=6,6+2=8,8*2=16,16-2=14
- 8 years agoHelpfull: Yes(9) No(1)
- 18
4,2,4
4*2,2*3,4*2
8*2,6*3,8*2
- 8 years agoHelpfull: Yes(6) No(1)
- sorry ans will be 14
- 8 years agoHelpfull: Yes(4) No(4)
- it is 1st divide in to set of 3,and the logic is (-2) for 2nd no. and (+2) for 3rd no.
so ANS:14 - 8 years agoHelpfull: Yes(4) No(1)
- 14.because 4-2=2
- 8 years agoHelpfull: Yes(3) No(0)
- 14 (-2,+2,*2)
- 8 years agoHelpfull: Yes(3) No(0)
- ans: a) 14
4,2,4
8,6,8
16,14,16 - 8 years agoHelpfull: Yes(3) No(0)
- Ans. 14
4-2=2
8-6=2
So 16 -14=2 - 8 years agoHelpfull: Yes(2) No(1)
- Ans:8
(4,2,4),(8,6,8),(16,8,__)
2,6,8 middle
4+4=8
8+8=16 - 8 years agoHelpfull: Yes(2) No(0)
- 14
first of all 4-2=2 then 2+2=
4, then 4*2=8,then 8-2=6, 6+2=8, 8*2=16, then 16-2=14 - 8 years agoHelpfull: Yes(2) No(1)
- 4,4-2,2+2,4*2,8-2,6+2,8*2,16-2=14
ans: a)14 - 8 years agoHelpfull: Yes(1) No(0)
- 4-2=2, 2+2=4, 4+4=8, 8-2=6,6+2=8,8+8=16
16-2=14 - 8 years agoHelpfull: Yes(1) No(0)
- Take first and Second Terms and subtract =2
Third=4=2^2
Take fourth and fifth terms and subtract=2
Sixth=8=2^3
Take seventh and eighth terms and subtract(Assume eighth term to be x) = 16-x which should be equal to 2 in accordance with the pattern recognized. Therefore, 16-x=2; x=16-2; x=14 ANSWER
And Ninth term should be 2^4=16 respectively. - 8 years agoHelpfull: Yes(1) No(0)
- 4-2=2,2+2=4,4*2=2,8-6=2,6+2=8,8*2=16,16-2=14
- 8 years agoHelpfull: Yes(0) No(0)
- 4-2=2,2+2=4,4*2=8
8-2=6,6+2=8,8*2=16
16-2=14,14+2=16,16*2=32,so the next number would be 14,16 and so on - 8 years agoHelpfull: Yes(0) No(0)
- (-2,+2,*2) is the pattern ans is 14
- 8 years agoHelpfull: Yes(0) No(0)
- 4-2=2+2=4*2=8 same logic apply
- 8 years agoHelpfull: Yes(0) No(1)
- Three pattern here
4,2,4 first next 4*2 2+4 4*2 =8,6,8
next step 8*2 6+8 8*2=16 14 16
so option b... - 8 years agoHelpfull: Yes(0) No(0)
- -2 then +2 then *by 2
hence 14 - 8 years agoHelpfull: Yes(0) No(0)
- its is a sequence of '-','+','*' so the answer will be A 14
- 8 years agoHelpfull: Yes(0) No(0)
- A 3 number series is being followed
(4,2,4) (8,6,8) (16,14,16)
#1 #2 #3
#1---->first -2 then +2 and then double the last digit 4 getting the first number of the next slot(#2)
- 8 years agoHelpfull: Yes(0) No(0)
- 14
leave middle number add first and 3rd 4+4=8,then 2nd and 3rd one 2+4=6
in the same way 8+8=16 , answer is 6+8=14 - 8 years agoHelpfull: Yes(0) No(0)
- 14 is the answer because 4-2=2 4*2=8 4+2=6 like that 16-2 =14
- 8 years agoHelpfull: Yes(0) No(0)
- 4-2=2,2+2=4,4*2=8,8-2=6,6+2=8,8*2=16,16-2=14
- 8 years agoHelpfull: Yes(0) No(0)
- a) 14
1st nd 3rd term is same and term in b/w 2 less than tem - 8 years agoHelpfull: Yes(0) No(0)
- (+2,-2,*2)
- 7 years agoHelpfull: Yes(0) No(0)
- 4-2=2,2+2=4,4*2=8,8-2=6,6+2=8,8*2=16,16-12=14 answer is 14
- 7 years agoHelpfull: Yes(0) No(0)
- Ans. 14 The rule which followed here is -2 and +2
- 7 years agoHelpfull: Yes(0) No(0)
