do the same for the above

Answer 1

Answer:

You can find the right answer in number series by taking the difference between consecutive pairs of numbers, which form a logical series. In this example, the differences between succeeding pairs of numbers are 1,2, 4, 8, 16, and 32. So, the next difference must be 64. 64, if added to the last number 65, gives 129, which is the correct answer.

I hope this gives some idea
