Just reverse the numbers nd then divide each digits for every numbers

24
reverse of 24 --42
divide first digit by 2nd digit 24 -- > 2/4 --> 1/2
nd then inverse it 2/1==2

folllow the same for 65
rev(65) -- 56
divide 6/5 ---> 1 1/5
inverse it 5/6

73
37
7/3-- 2 1/3
3/7

so d next terms ll be 2 1/3, 3/7

Look upon the series carefully
24, 42, 1/2, 2, 65, 56, 1 1/5, 5/6, 73, 37,?

First no. 24
reverse of the no. 42(2nd no.)
divide first digit by 2nd digit 24
2/4 = 1/2
& then inverse it 2/1 = 2

similarly
fifth No. = 65
reverse = 56
divide first digit by 2nd digit 65
6/5 = 1 1/5
& then inverse it 6/5 to 5/6

again similarly
ninth no = 73
reverse = 37
divide first digit by 2nd digit 73
7/3 = 2 1/3
& then inverse it 7/3 to 3/7

so answer will be 2 1/3 and 3/7

@tejaswi

its not 11/5 ... its 1 1/5(mixed fraction) so 1*5+1/6

nd then inverse it 2/1==2

Saraswathy  (10 years ago)

sorry 1 1/5 ( mixed fraction)

so 1*5+1/5= 6/5

Is this solution Helpfull? Yes (1) | No   

Rohit Agarwal  (10 years ago)

next number in series is 7/3,3//7

here if we see that 24,42 ,1/2,2
than 2/4=1/2
4/2=2

similiarly

65,56,6/5,5/6

so here next term is 6/5 and 5/6


so on..

its all reverse and mirror image
2442
24-->2/4=1/2
42-->4/2=2
.
.
7337
73-->7/3=2 1/3
37-->3/7=3/7... so the next series is 2 1/3,3/7.

24 42, 1/2,2 ---- 1/2 is 2/4 and 2 is 4/2
65 56, 11/5 5/6 --- straight forward to understand
by same logic --- 73. 37. 7/3
