Yes, I agree @Topcoder.
A is the correct answer.
Because:
3,
3 * 2 - 1 = 5.
3 * 4 - 1 = 11.
3 * 5 - 1 = 14.
3 * 6 - 1 = 17.
But
3 * 7 - 1 =20 So option A is correct.

It can also be like this.
3+2 = 5, 5+6 = 11, 11+3 = 14, 14+7 = 21.
So according to this, 17 is "Find the odd number".
The first number is increased by 2 followed by an increase by 6. The next number is increased by 3 followed by an increase by 7 and so on.
3+2 = 5, 5+6 = 11, 11+3 = 14, 14+7 = 21.
So according to this, 17 is "Find the odd number".
The first number is increased by 2 followed by an increase by 6. The next number is increased by 3 followed by an increase by 7 and so on.
