To find the sum of the sequence, we need to add the numbers in the sequence together. However, since the numbers are in hexadecimal notation, we need to convert them to base 10 first.

11ebb63d = 3,245,224,189
1bbd8f3c = 465,931,004
b8515d0f5454503f = 14,382,975,757,004,543,647
TB8475 = 46,638,453
11 = 17

Adding all these numbers together we get:
3,245,224,189 + 465,931,004 + 14,382,975,757,004,543,647 + 46,638,453 + 17 = 14,382,979,745,386,108,310

However, since the sum is given in hexadecimal notation and the possible answers are given in decimal notation, we need to convert the sum back to hexadecimal to compare it to the answer choices.

14,382,979,745,386,108,310 in hexadecimal notation is:
11ebb63d_1bbd_8f3e_b852_546c4fe73c_TB8475_11

Comparing this to the sequence given, we can see that the only difference is in the fourth set of digits (b851 vs. b852). The difference between these two numbers is -1, which means that the sum of the sequence is -1 in decimal notation.

Therefore, the answer is choice C: -135. In each position of the sequence, we add the two digits from each number that are at that position. For example, in the first position, we add 1 and 1 to get 2. Doing this for each position, we get the sequence: 2-16-11-4-17-14-6-4-4-9. Adding all of these together, we get -135.
