What is the sequence for 6,12,18,24

an = 6n

Step-by-step explanation:

6, 12, 18, 24

Take the 2nd number minus the first number, 3rd minus the second, etc

12-6 = 6

18-12 = 6

24-18 = 6

The common difference is 6

The formula for an arithmetic sequence is

an = a1+d (n-1)

where a1 is the first term

d is the common difference

n is the term number

an = 6+6 (n-1)
