3/2, (3^2/2^2=9/4) and 9/4 is then written as 2 1/4.
Therefore for 8/3 the next term will be 7 1/9 which is equal to 8^2/3^2 and the next term will be 64/9
answer is 7 1/9

33+8 = 41,
46+21 = 67 ,
72+ 47 = 119,
124+ ? = ?
Now, take 2nd, 5th, 8th and 11th term separatly
i.e., 8, 21, 47, ?
8+ 13 = 21
21 + (13*2) = 47
Similarly, 47 + (13*2*2) = 99 i.e, ? =99

15 3/4,16,26,9 1/5,9,19,64 2/3,65,75,30 3/8,-- turns into -- 63/4, 16,26,46/5,9,19,194/3,65,75,270/8

now (16,26) , (9,19) , (65,75) have difference of 10
also new these sets are coming in periodic gap of one fraction number .
new series obtained will be

(16,26) , (9,19) , (65,75)
16-9= 7 (decreasing)
26-19=7 (decreasing).. 7 is the gap so ,

65 -7 = 58
75-7= 68

Hence the number is 58

Mallika Bhaskar  (7 years ago)

the last series ... 33,8,41,46,21,67,72,47,119,124,--

1. 33+8=41
similarly add n get third number.. 46+21=67
72+47=119
124 +y = a... let it be y and a.. the next two terms..

2. take difference of the results got in 1.
like 67-41=26 i.e. 26*1
119-67=52 i.e. 26*2
similarly next difference wud be 26*3=78...
so a-119=78...

now add and get a= 119+78=197

now y will be 197-124=73..


so series wud be 33,8,41,46,21,67,72,47,119,124,73,197

33+8=41
46+21=67
72+47=119
Now,see all 2nd term in group 21=8+13*1,47=21+13*2,so ans=47+13*3=47+39=84 ans.84

33+8=41
46+21=67
72+47=119
124+?=?
now if u consider 2nd,5th,8th and so on then we will get 8,21,47.. look diff between those no is multiple of 13 so we can add 47+13*3=46 so the answer 86 so series will be 8,2147,86
then the final series will be
33,8,41,46,21,67,72,47,119,124,86,210 and so on... 86 is the ans
