Write the explicit rule by writing each term as the product of the first term. 1.) N 1 2 3 4
F(n) 3 15 75 375

2.) 40, 60, 90, 135,

1 f(n) = 3(5)^x-1

2 f(n) = 40(3/2)^x-1

Step-by-step explanation:

The first number in the sequence, times the (multiplicative factor)^ x-1 is the rule for geometric sequences.
