blank and
blank. fill it in

Respuesta :

Answer:

[tex]8.5,7.15,5.8,4.45,3.1,...[/tex]

Step-by-step explanation:

The first step to solve this question is to analyze the given sequence.

We can notice that the difference between 8.5 and 7.15 is

[tex]8.5-7.15=1.35[/tex]

And again the difference between the second and the third term is :

[tex]7.15-5.8=1.35[/tex]

One way to describe all the numbers in the sequence is by using a formula.

We can write :

Given the sequence [tex]a_{0},a_{1},a_{2},a_{3},...[/tex]

[tex]a_{n}=8.5-(1.35)n[/tex] with [tex]n[/tex] ∈ I[tex]N_{0}[/tex]

For example :

[tex]a_{2}=8.5-(1.35).2=5.8[/tex]   which verifies our original sequence.

We can obtain any term we want of the sequence.

Some of the terms that complete the sequence are :

[tex]8.5,7.15,5.8,4.45,3.1,...[/tex]
