In order for us to determine the value of O(20), we just have to substitute 20 to the n’s of the function.

                                                O(n) = 2n – 1

Substituting,

                                              O(20) = 2(20) – 1= 39

Thus, the answer is letter C. It should be noted also that this is also the 20th odd number, so letter B is also acceptable.
