The next number in the sequence is 9. The rule is to add 2, then subtract 1, add 2, subtract 1, and so on.
The next number is 20, because 5 plus 1 is 6 and 6 plus 2 is8 and 8 plus three is eleven and eleven plus four is fifteen etc.
add up al digits in followed order: 6+3 = 9+3=12 12+9=21 21+12=33 33+21 = 54
Missing nr is 33

If you convert those numbers into letters, it spells "Love You".
The number you are looking for is 12. Reversing the digits gives you 21 75% of 12 is 9 12 + 9 = 21
find the missing number 8-4-9 14-5-2 18-1-? i think it's 2 then the sum of all numbers in each set is 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...
Let's represent the number as "x". The given equation can be written as 2x - 12 = 30. Adding 12 to both sides, we get 2x = 42. Finally, dividing both sides by 2, we find that x = 21. So, the number is 21.
(21/x) (12/100)= 175
