You're subtracting by 9.
-9
n + 18 = 27 subtract 18 to 18 and 27 18-27=9 n = 9
27-18=9.
It is -9 because the numbers are decreasing by 18 each time
The number that can be added to 18 to get 27 is 9.
9,18,27,36,45,54
9, 18 and 27 are three numbers that have a GCF of 9
-9
n + 18 = 27 subtract 18 to 18 and 27 18-27=9 n = 9
27-9 = 18
The greatest common factor of 9, 18, and 27 is 9. Since 9 is a factor of both 18 and 27, it is automatically the GCF of the set.Factors of 9: 1, 3, 9Factors of 18: 1, 2, 3, 6, 9, 18Factors of 27: 1, 3, 9, 27GCF (9, 18, 27) = 9
21-3=18 18/2=9 9*3=27 that is the pattern so after the 36 it should be 33
27-18=9.
It is -9 because the numbers are decreasing by 18 each time
