Read Solution (Total 14)
-
- 11 because allothers are divisible by 4
- 10 years agoHelpfull: Yes(17) No(1)
- ans:768 is the odd no
11
11*4+4=48
48+2+4=100
100+4-16=384
384*2-16=752
752*4+64=3072 - 10 years agoHelpfull: Yes(15) No(14)
- 100 IS ODD BCOZ
11*4+4=48
48*2+4=100
100 doesnot make any above type of arrangment
384*2=768
768*4=3072 - 10 years agoHelpfull: Yes(6) No(11)
- TAKE IT IN TWO GROUPS OF THREE
FIRST GROUP(11,48,100)
SECOND GROUP(384,768,3072)
SECOND GROUP
384*2=768
768*4=3072
MAKES A SERIES
BUT IN FIRST GROUP IT DOES NOT MAKE A SERIES BECAUSE OF 11
IF 11 REPLACED WITH 12.5 THEN THEY MAKE A SERIES AS IN SECOND GROUP
THEREFORE 11 IS ODD. - 10 years agoHelpfull: Yes(5) No(1)
- ans is 11 its the only odd no
- 10 years agoHelpfull: Yes(3) No(4)
- 11 prime no
- 10 years agoHelpfull: Yes(2) No(0)
- 11 becausea an odd number
- 10 years agoHelpfull: Yes(2) No(0)
- correct series is
6, 12, 48, 100, 384, 768, 3072....
Each even term of the series is obtained by multiplying the previous term by 2.
2nd term = (1st term) x 2 = 6 x 2 = 12
4th term = (3rd term) x 2 = 48 x 2 = 96.
6th term = (5th term) x 2 = 384 x 2 =768.
4th term should be 96 instead of 100. - 9 years agoHelpfull: Yes(2) No(1)
