There are 60 passengers in the first cabin of the train, 100 in the second and 140 in the third train cabin. Number of passengers in the 16th cabin is?
- 700
- 660
- 640
- None of these
Explanation
The pattern: 60, 100, 140... increases by 40 each cabin.
That’s an arithmetic sequence: a₁ = 60, d = 40
16th term = 60 + (16-1)×40 = 60 + 600 = 660
