Quizplus · Accepted Answer

The sequence contains hexadecimal numbers which can be converted to decimal as follows: 
11ebbed0 = 3,277,477,360 
ca25c590 = 3,251,520,144 
8acbc5f7 = 2,322,452,471 
e683b8 = 15,145,528

Summing these up gives: 
3,277,477,360 + 3,251,520,144 + 2,322,452,471 + 15,145,528 = 8,866,595,503 
Converting this back to hexadecimal gives: 
8,866,595,503 = 0x20ebbedf

The last two digits of this hexadecimal sum are 0x3f, which is equivalent to 63 in decimal. 
Adding this to the given sequence number TB8253_11, we get: 
63 + 11 = 74

Therefore, the answer is A) 176. The sequence can be broken down into groups of two digits: 11, eb, be, d0, ca, 25, c5, 90, 8a, cb, c5, f7, 37, e6, 83, b8, TB, 82, 53, and 11.
Converting each group to decimal form gives: 17, 235, 190, 208, 202, 37, 197, 144, 138, 203, 197, 247, 55, 230, 131, 184, 69137, 130, 83, and 17.
Adding all of these values together gives a final sum of 176.
