If a progression goes 15 __ 21, then the missing number will dictate how the pattern increases with every number. If the missing number is 18, this means that the numbers go up in threes. The pattern would continue 24, 27, 30, 33...
Tape #15
To find the missing number in the sequence 10, 15, 28, we can look for a pattern in the differences between the numbers. The difference between 10 and 15 is 5, and the difference between 15 and 28 is 13. If we assume a pattern in the differences, the missing number could be 21, which fits as the average of 15 and 28. Thus, the sequence could be 10, 15, 21, 28.

To find the missing number in a data set with a mean of 15, you need to know the total number of values (n) in the data set and the sum of the existing numbers. The mean is calculated as the sum of all values divided by n. If you have the sum of the existing numbers, you can rearrange the formula: missing number = (mean × n) - sum of existing numbers. Without additional information, the exact missing number cannot be determined.
The logic behind this level is that the part of the figure that is missing is where the number is on the keypad, so for the first figure over the door, the upper left corner is missing, where the number 1 is on the keypad. For the second figure, the right middle is missing, which is where the 6 is, etc. Type in the pass code 1643 to open the door.
(Divide both sides by 6)x = 2.5
E.g. 6 + _ = 15. To find the answer, subtract 6 from 15 = 9. Answer: 6 + 9 = 15 This may be relevant or irrelevant to the question.

x = missing number x/10 = 15 operate on the equation, doing the same operation to both sides, to isolate x (namely, multiply both sides by 10)
If you convert those numbers into letters, it spells "Love You".
