21 = (.12)(x) 21 / .12 = x Answer: 175
12. you're doing multiples of 3 and the tens and ones places are just reversed in the writing- 3 6 9 12 15 18 21=3 6 9 21 51 81 12
21
The number at the midpoint of these two numbers is (15 + 27)/2 = 21
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...

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.
