There are two series. They are-
17,44,108,? and 27,64,138
We have to find ? mark so that we find the 7th term of the series
For first series
2nd term=17*2+10=44
3rd term=44*2+20=108
so, 4th term=108*2+30=246
For second series
2nd term= 27*2+10=64
3rd term=64*2+10=138
So, option 9)246 is the right answer

here increase second number by 10
you will get 17+10=27
17+27=44
44+20=64
44+64=108
108+30=138
108+138=246

if we give index number to each of the given number , we get our series as :

index no - given no
1 - 17
2 - 27
3 - 44
4 - 64
5 - 108
6 - 138
now , through inspection we can say that difference between number with odd index with even index is multiple of 10 i.e. 27-17 = 10 , 64-44 = 20 , 138-108 = 30
&
difference between number of even index with odd index is previous number stored at odd index i.e.
44-27 = 17 (located at index 1) , 108-64 = 44 (located at index 3) .
hence , next number will be 138 + 108 = 246

The differences between the 1st and 2nd number, the 3rd and the number and the 5th and 6th number is in the multiples of 10 respectively
i.e., 27-17=10
64-44=20
and 138-108=30
Now, the first two numbers are added to get the 3rd number i.e.,
17+27=44
