Question

Write the nth term of the geometric sequence as a function of n

Answer 1

ANSWER CHOICES:
an=2(5)^(n-1)
an=5(2)^(n-1)
an=2(1/5)^(n-1)
an=-3+5n
an=2(5)n

Answer 2

A2=5*A1=5*2
A3=5*A2=5*5*2
A4=5*A3=5*5*5*2
...
An=2*5^(n-1)

Answer 3

using formula :
a1 = 1st term = 2
common ratio = r = a(k+1)/ak = 5
and general term = \(\large a_n = a_1r^{n-1}\)
