Select the number from among the given options that can replace the question mark (?) in the following series.
100, 98, 104, 92, 112, ?
Here we are taking the middle row.
2+4 = 6
6+6 = 12
12+8 = 20
So 20+10 = (112-?)
30 = (112-?)
? =Â 112-30
= 82
So here '82' will come in place of the question mark.
