do we have an official answer?

If the distances between consecutive ticks in the above number line are the same, which of the following points represents \(2^{11}\)?

A. A
B. B
C. C
D. D
E. E

The length of each segment is (2^10 - 2^9)/2 = 2^9(2 - 1)/2 = 2^8.

The distance between 2^10 and 2^11 is 2^11 - 2^10 = 2^10(2 - 1) = 2^10, which is equal to the length of 2^10/2^8 = 4 segments.

Four segments from 2^10 reach point D.

Answer: D.
