11, -10, 9
12, 10 and 15 the are alternatively increased by 2 and 3
The factors of the numbers are 12: 1, 2, 3, 4, 6, and 12 15: 1, 3, 5, and 15 30: 1, 2, 3, 5, 6, 10, 15, and 30 The GCF of the three numbers is the largest number that is a factor of all three numbers, which is 3.
Each number is three times the previous number.
12 & 15
11, -10, 9
12, 10 and 15 the are alternatively increased by 2 and 3
The next three numbers in the sequence are 23, 25, and 27.
The factors of the numbers are 12: 1, 2, 3, 4, 6, and 12 15: 1, 3, 5, and 15 30: 1, 2, 3, 5, 6, 10, 15, and 30 The GCF of the three numbers is the largest number that is a factor of all three numbers, which is 3.
Each number is three times the previous number.
The pattern is add three and then multiply by three. The next number is 174.
12 & 15
The numbers are halving each time, so the next three are 60, 30 and 15.
42 123 243
