What should come at the place of the question mark (?) in the following series? 2, 3, 8, 9, 26, 27, ?

1. 54
2. 56
3. 80
4. 82

Correct answer: 80

Solution

The pattern is 2, 3; 8, 9; 26, 27; where the first term of each pair is obtained by multiplying the previous first term by 3 and adding 2: 2→8→26→80. Each is followed by the next integer. Hence the next term is 80.
