What will come in place of question mark (?) in the given number series ?
150, 102, 70, 46, 26, ?
The difference between the difference of each consecutive term is in decreasing order of power of 2 , starting from 16.
150-102 =48
102-70 = 32
70-46 = 24
46-26 = 20
The difference of differences
48-32=16
32-24=8
24-20=4
The next difference of difference must be 2.
Hence the next term in the series must be 18 less than 26 which is 8.
Option C is the correct answer.
