PLEASE HELP ME WITH MATH Write an explicit formula for the following sequence. Then generate the first five terms.
a = 625, r=0.2
Choose the correct explicit formula for the sequence.
O A. 2. = 0.2.(625)n-1 n> 1
O B. 2. = 625. (0.2)" – 1 for n21
O C. an = 625n-1 • (0.2) for n 21
OD. 2. = 625. (0-2)" for n> 1
Generate the first five terms.
24 = (Simplify your answer.)
az - (Simplify your answer.)
a3 = (Simplify your answer.)

Step-by-step explanation:

The explicit formula for a geometric sequence with first term a1 and common ratio r is ...

In this problem, you are given a1=625 and r=0.2. Filling in those values gives the explicit formula ...

You can either evaluate this function for values of n = 1 through 5, or you can multiply each term by the common ratio to get the next.

  a1 = 625

  a2 = 625·0.2 = 125

  a3 = 125·0.2 = 25

  a4 = 25·0.2 = 5

  a5 = 5·0.2 = 1

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

a is the right answer
