Devendra Marghade   8 years AGO

Take a group of 3 numbers a,b,c
Here b-c=c-a
(32, 52, 42) => 52-42= 42-32
(64, 72, 68) => 72-68= 68-64
(84, 92, 88) => 92-88= 88-84
(96, 98, x ) => 98- x= x -96
So to get the equal difference x=97

Mukund Manohar   8 years AGO

There are 4 groups of 3 numbers
In every group,the difference between 2nd term and 1st term is double the difference between 2nd term and 3rd term
52-32=20
and 52-(20/2) = 52-10 = 42
Similarly,in (64,72,68)
72-64 = 8
and 72 - (8/2) = 72 - 4 = 68
In (84,92,88)
92-84 = 8
and 92-(8/2) = 92-4 = 88
Now, 98-96 = 2
98-(2/2)=98-1 = 97

taking the sequence in group of 3 from left to right

1st 3 term of sequence:
1st term + 10 = 3rd term and 3rd term+10= 2nd term

similarly in 2nd group of sequence ie- next 3 terms
1st term +4= 3rd term and 3rd term+4=2nd term

similarly for 3rd group:
1st term+4= 3rd term and 3rd term +4= 2nd term

now in last group 3rd term is missing so it has to be,
1st term +1=3rd term and 3rd term +1=2nd term

Numbers can be divided in groups of three, third number being the average of first two. See ; (32+52) /2 =42
(64+72 ) /2 =68
(84+92) /2 = 88
(96+98) / = 97
Hence 97 is correct answer

The ans is 7 bcoz take the first three terms 32,52,42
52-32=20
20/2=10
52-10=42
likewise take the next three terms
64,72,68
72-64=8
8/2=4
72-4=68
so the given last three terms 96,98,?
98-96=2

in series of three like (32, 52, 42) difference is 32+20=52 and then 52-42=10 here second one is half minus of 20 as 20 half is 10 so we subtract
just as 64+8=72 similarly 8 divide by 2 =4 so we minus it 72-4=68,
84+8=92 and 92-4=88
