Step-by-step explanation:
srry if I'm worng. hop it helped
I could be a hw helper if I want
I would pick A because if you look and plug in, you would get all your answers.
A)an=n/(n+1) n= 1,2,3,4,5
a(1) = 1/(1+1) =1/2
a(3) = 3/(3+1) = 3/4
An = a1 * r^(n-1)
a1 = first term = -5
r = common ratio = -4
so ur formula is : an = -5 * -4^(n-1) <==
