Series Problem like 4 12 x 44 46 132 134. Find x?
Read Solution (Total 15)
-
- 44+2=46
132+2=134
lly 12+2=14 so x=14; - 14 years agoHelpfull: Yes(19) No(41)
- divide odd places by 2 and even by 4 in the whole series u get....
2,3,(x/2),11,23,33.....
but try to make the seies increasing....
so (x/2=7)
hence x=14.... wat say??? - 14 years agoHelpfull: Yes(5) No(18)
It seems every odd number is 2 more than the one before it. By that rule,
x = 14

- 134-2=132
132/3=44
46-2=44
44-2=42
42/3=14
14-2=12
12/3=4 - 12 years agoHelpfull: Yes(5) No(1)
- here divide every numbers by 2
2,6,x,22,23,66,67,
now from above we guess that.. next term will multiple of 2 of following numbers.. 102,103,104,106,107,122,123,124,125,166,167,.....
so that x=7 which multiple of 2 so ans is 14.
Now whole series look like 4,12,14,44,46,132,134,204,206,208,212,214,244,246,250,322,324......... - 13 years agoHelpfull: Yes(2) No(0)

- 14
4=2*2
12=2*6
x=2*7
44=2*22
46=2*23
132=2*66
134=2*67
- 13 years agoHelpfull: Yes(1) No(1)
- 14
as 44+2=46
132+2=134
12+2=14 - 13 years agoHelpfull: Yes(0) No(0)
- 14....as the series proceed we see that

- anw is x=14;
the diff b/w 44 & 46 is 2
n 132 &134 is 2
so the value of x is 2 - 12 years agoHelpfull: Yes(0) No(1)
- x=14 as every odd positioning number(except 1st)in that series.
- 12 years agoHelpfull: Yes(0) No(0)
- It must be 14 because 4*3=12 and 44*3=132 and after 44 we have 46 so after 12 it must be 14.
- 12 years agoHelpfull: Yes(0) No(1)
- 44+2=46 and 132+2=134 so we can say that
12+2 = 14 - 12 years agoHelpfull: Yes(0) No(0)
- 14.4*3=12 and it is increased by 2.44*3=132. it is increased by 2 so we get 134.
- 12 years agoHelpfull: Yes(0) No(0)
- ans is 14.... as
4*3=12
12+2=14
14*3=42
42+2=44
44*3=132
132+2=134
