Prime numbers 2, 3, 5, 7, 11, 13 are to be added successively.

So, 165 is wrong.

Terms at odd places are 5, 6, 7, 8 etc. and each term at even place is 16.

So, 9 is wrong.

Subtract 20, 25, 30, 35, 40, 45 from successive numbers.

So, 0 is wrong.

Each number is a composite number except 11.

Subtract 1, 3, 5, 7, 9, 11 from successive numbers.

So, 34 is wrong.

The differences between two successive terms from the beginning are 7, 5, 7, 5, 7, 5.

So, 40 is wrong.

The terms are alternatively multiplied by 1.5 and divided by 3. However, 18.5 does not satisfy it.

The numbers are 7 x 8, 8 x 9, 9 x 10, 10 x 11, 11 x 12, 12 x 13.

So, 150 is wrong.

The numbers are squares of odd natural numbers, starting from 5 up to 15.

So, 36 is wrong.

Each number is twice the preceding one with 1 added or subtracted alternatively.

So, the next number is (2 x 261 + 1) = 523.
