Question

Write a linear equation that represents the arithmetic sequence 10, 8, 6, 4, ... A. an = 10 + 2(n + 1) B. an = 10 + 2(n – 1) C. an = 2 + 10(n – 1) D. an = 10 – 2(n – 1)

Answer 1

Here is the equation buddy

Answer 2

Answer: (D) an=10-2(n-1)

Step-by-step explanation:

an=a+(n-1)d

Here a=10 and d=8-10= -2

So an=10+(n-1)(-2)

an=10-2(n-1)
