Question

G (1) = 2.2 g(n) = g(n-1) * (-5) Find an explicit formula for g(n)?

Answer 1

Answer:

Step-by-step explanation:

g(2)=2.2*(-5)

g(3)=2.2*(-5)^2

........................

g(n)=2.2*(-5)^(n-1)

Answer 2

Answer:

Step-by-step explanation:

g(1)=2.2

g(n)=g(n-1)*(-5)

$\frac{g(n)}{g(n-1)}=-5\\so~r=-5\\first term=2.2\\t_{n}=ar^{n-1}\\g(n)=2.2(-5)^{n-1}$
