Select the number that can replace the question mark (?) in the following series.
Here the first and the second terms will be added to form the third term. Similarly the second and the third terms will be added to form the fourth term. With the same logic, the upcoming terms will be formed.
43+31 =Â 74
31+74 =Â 105
74+105 =Â 179
105+179 =Â 284
So 284 will come in place of the question mark.
