18, 14, 10, 6, 2,…
A. subtract 4 from the previous term
B. add 4 from the previous term
C. divide the previous term by 4
D. divide the previous term by 4

Answer 1

Option A

It's an arithmetic sequence

• First term=a=18
• Common difference=d=4.

Rule is

`\\ \rm\hookrightarrow a_n=a+(n-1)d`

`\\ \rm\hookrightarrow a_n=18+(n-1)4`

Answer 2

It is A

Explanation:

Because 18 to 14 is subtracting 4 and then it goes 14 to 10 which is another 4. Hope you ace the quiz or test or whatever your doing hope it helps.
