M is the sum of the reciprocals of the consecutive integers from 201 to 300, inclusive. Which of the following is true?

If all 100 terms were equal to 1/200, then the sum would be 100/200=1/2, but since actual sum is less than that, then we have that M<1/2.

Can I calculate total sum using standard formula for AP:

The general sum of a n term AP with common difference d is given by \(\frac{n}{2}(2a+(n-1)d)\)

Here: difference is zero and first term is 1/300. Total no of terms =100

Or, did you simply factor out 1/300 common and multiplied it by no of terms ie 100?
