Q. What is the next number of the following sequence.
18,24,5,21,27,8,4,24,30,...
Read Solution (Total 4)
-
- 18 24 5
21 27 8 4
24 30 _ _
in each column, the difference between upper number and lower number =3,,
so next term in the series = 11 - 11 years agoHelpfull: Yes(21) No(6)
- 18-24=-6
24-5=19
21-27=-6
27-8=19
...
24-30=-6
30-x=19
x=11 - 11 years agoHelpfull: Yes(17) No(13)
- 7
as becoz after every even two multiples of three the privious multicand is used as
3*6=18
3*8=24
as both multiples are even we use the multipllicand of the previous one that is 5.
and for odd multiples we use the next evn multiplicand - 11 years agoHelpfull: Yes(0) No(1)

BUT 8-4=4 AND 4-24=-20 - 10 years agoHelpfull: Yes(0) No(0)
