Answer:

Step-by-step explanation:
When variables have negative exponents, switch their positions.

The 3rd one because when you find the absolute value of a number, it will always be positive. So the list would be 3.5, 4.2, 9
the explicit formula for aₙ the nth term of the sequence will be:
Step-by-step explanation:
The explicit formula of geometric sequence is of the form:

where a₁ is the first term and r is the common ratio.
We are given:
a₁ = 6
r = 2/3
Putting values in the formula:

So, the explicit formula for aₙ the nth term of the sequence will be:
