Multiply by 3. Then subtract 10.

Without further terms in the sequence, it is impossible to determine what the rule in the sequence is.
Check the differences between consecutive numbers.
There are not many numbers in the sequence here, but one solution that holds for this series is to take the first number, double it to get the second number, add 1 to get the next number, and repeat. So, the pattern would continue as follows: 1, 2, 3, 6, 7, 14, 15, 30, 31, 62, 63
The number must be divisible by 2 and by 7.
Each number is decreasing by half.
Just work the problem backwards. The answer is 248. Something was divided by 12 in order to get it. If we MULTIPLY 248 by 12, we will find that number. We get 2,976. Now, we need to ADD 14, since 14 had originally been subtracted from the number we're looking for. Adding 14 we get 2,990.

Each time you add 7 chairs perhaps?
