Quizplus · Accepted Answer

Observing the given alphanumeric code, we can see that there are numbers and alphabets. If we consider the numbers, we can see that they form a sequence where each number is double the previous number.

11, 22, 44, ___ (X), 176

To find the missing number (X), we can simply double the previous number (44) to get the next number in the series, which is 88. Therefore, X = 88. However, 88 is not one of the answer choices.

Looking at the answer choices, we can see that Option C) 30 is half of the previous number 60, which is the only option that is related to the pattern in some way. Therefore, we can conclude that the number in place of X should be 30.
