Q. What is the next number of the following sequence
33,8,4,46,21,67,47,119,124..........?
Read Solution (Total 7)
-
- 33+8=41
46+21=67
72+47=119
124+?
Now see the difference b/w 33 and 46 is 13 same in 8 and 21
after that 26 is the difference 46 and 72 and so on...
then 52 is the differnce
it means diff is doubled every time
hence 47+52=99 Ans - 11 years agoHelpfull: Yes(8) No(0)
- this series is incomplete . it is as
33,8,41,46,21,67,72,47,119,124,? - 11 years agoHelpfull: Yes(6) No(0)
- 33+8=41----(1)
46+21=67-----(2)
72+47=119----(3)
124+x=?-----(4)
1&2 difference(67-41=26)
2&3 difference(119-67=52)
3&4 i can add 52+26=78,78 is the difference of 3&4,so 119+78=197
now take (4)
124+x=197
x=197-124
x=73
ans:73

- 33+8=41----(1)
46+21=67-----(2)
72+47=119----(3)
124+x=?-----(4)
1&2 difference(67-41=26)
2&3 difference(119-67=52(26*2))
3&4 52*2,104 is the difference of 3&4,so 119+104=223
now take (4)
124+x=223
x=223-124
x=99
ans:99 - 11 years agoHelpfull: Yes(3) No(0)
- wrong series
- 11 years agoHelpfull: Yes(1) No(1)
- absolutely wrong....:/
- 11 years agoHelpfull: Yes(1) No(1)
- 33+8=41 (46-33=13) (21-8=13)
46+21=67 (72-46=26) (47-21=26)
72+47=119 (124-72=52) here to make the difference must be 52 so 47+52=99,add 99 to 124 then u will get the series next number
124+99=223 so series term is 223 - 11 years agoHelpfull: Yes(0) No(0)
