Question

What is the formula for the following arithmetic sequence?
12, 6, 0, -6, ...
a. an = 6 + 12( n - 1)
b. an = 12 + 6( n - 1)
c. an = 12 + (-6)( n - 1)
d. an = -6 + 12( n - 1)

Answer 1

Step-by-step explanation:

Formula to find arithmetic sequence

=a+(n-1)d

a is the first no

d is the common difference

Here

a=12 and d=-6

That is formula for this sequence= 12+(-6)(n-1)

I hope this helped
