Answer:

No solution

Step-by-step explanation:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 2 gives the next term. In other words, a n +a1 ⋅ r n -1

Geometric Sequence: r = 2

The series given has a value of r such that r > 1 or r < − 1. Therefore, the infinite sum cannot be calculated.

Explain what |-13| means and how to simplify.

poizon [28]

The two bars ( | | ) symbolize absolute value

Absolute value is essentially just making the number given positive.

If the given number is already positive then the absolute value is the same as the original number

|-13| is 13

The absolute value of -13 is 13
