What is the missing number 16 4 12 36 9 27 44 11 -?

To find the missing number in the sequence 16, 4, 12, 36, 9, 27, 44, 11, we can look for a pattern. The first set of numbers appears to alternate between two sequences: the first sequence (16, 12, 9, 44) and the second sequence (4, 36, 27, 11). Following this pattern, the missing number, which follows the last number in the second sequence (11), should be 33. Thus, the missing number is 33.

What is the average of 18 12 13 17?

To find the average of a set of numbers, you add all the numbers together and then divide by the total number of values. In this case, the sum of 18, 12, 13, and 17 is 60. Since there are 4 numbers in the set, you divide 60 by 4 to find the average, which is 15.
