- 04
4,02,42,82,23,63,?
will become
4,02,42,82,23,63,04 multiples of 4 with digits reversed. - 11 years agoHelpfull: Yes(50) No(3)
- 4*(4+0)=4
4*(4+1)=20 i.e 02
4*(4+2)=24 i.e 42
4*(4+3)=28 i.e 82
4*(4+4)=32 i.e 23
4*(4+5)=36 i.e 63
hence
4*(4+6)=40... i.e.ans:04 - 11 years agoHelpfull: Yes(48) No(24)
- write the numbers in reverse order 4,20,24,28,32,36
- 11 years agoHelpfull: Yes(20) No(4)
- the sequence can be interpreted as 4,20,24,28,32,36 all these nos are multiples of 4 so the next number in the series is 04
- 11 years agoHelpfull: Yes(3) No(0)
- ans 103 leaving 4 all other 3 are the addition of 40 and the same follows for next 3
- 11 years agoHelpfull: Yes(0) No(8)
- 6+4= 0 carry 1. 1+3=4 => 04
- 9 years agoHelpfull: Yes(0) No(0)
- 4*(4+0)=4
4*(4+1)=20 i.e 02
4*(4+2)=24 i.e 42
4*(4+3)=28 i.e 82
4*(4+4)=32 i.e 23
4*(4+5)=36 i.e 63
the next number must be 40 and reversed 04
so ans is 04 - 6 years agoHelpfull: Yes(0) No(0)
