there are three different problems so don't answer them as one..
2006-10-11 00:08:15 · update #1
1st one- times 3 i.e 4x3=12x3=36...
2nd one- subtract 8 i.e. 27-8=19-8=11...
3rd one- I think yhe no.s are repeating...i.e. befor 7 there must be 4 so 7+4=11+7=18+11=29+18=47...

4*3=12 12*3=36 36*3=108
(multiply by 3)
27-8=19 19-8=11 11-8=3
(subtract 8)
7+4=11 11+7=18 18+11=29
(add the previous no)

Compare each term with the previous term; subtract #1 from #2, then #2 from #3 and so on. If it's a linear progression then the result will be the same every time. If that does not work, try division instead of subtraction. It's really easy; I did all three in my head in seconds.

THe number patter for 4, 12, 36, 108
let 4 = x1
12 = x2
36 = x3
108 = x4
x2 = 3(x1)
x3 = 3(x2)
x4 = 3(x3)
or 3x(x1, x2, x3)
for 27, 19, 11, 3
let 27 be a, 19 be b, 11 be c and 3 be d
a=27
b=a-8
c=b-8
d=c-8
and so on

for the first one, you multiply the previous number by three to get the next one.
in the second one, there is a patern. 8-8-8 drop.
for the last one, the fibonnaci sequence. 7+11=18 18+11=29

4 + 8 = 12- - - - - - 4 x 3 = 12
12 + 24 = 36- - - - - 12 x 3 = 36
36 + 72 = 108- - - - - 36 x 3 = 108
- - - - - - - - - - - - - - - - - - - - -
28 - 8 = 19
19 - 8 = 11
11 - 8 = 3
-- - - - - - - - - - - - - - - - - - -
7 + 4 = 11

1 ans is 324 every no is multipied my 3
2 ans is -5 as every no is subtracted by 8
3 ans is 47 as the no's are added with the previous element {7+11,18+11,29+18=47}
