Find a formula for the nth term in this

arithmetic sequence:

a1 = 8, a2 = 4, a3 = 0, 24 = - 4, ...

an = - 4n + 12

Step-by-step explanation:

hello:

the nth term in this arithmetic sequence is : an = a1 + (n - 1) d

a1 = 8 d = a2-a1 = 4-8 = - 4 (common difrence)

an = 8 + (n - 1) (-4) = 8 - 4n + 4

an = - 4n + 12
