Answer: The fiveth term is 81/4

Step-by-step explanation: The general formula for the geometric sequence is Tn=ar^n-1

Where a is the 1st term and r is the ratio.

We get the ratio by multiplying terms 2 by term 1 so the ratio is 3/2.

The general formula is Tn=4 (3/2)^n-1

To get the fiveth we have the substite 5 on n to get 81/4.

Answer:

Step-by-step explanation:

Angle QPR is a central angle. When a central angle intercepts an arc of a circle, the arc and the angle have the same measure. So the minor arc, the one that is less than 180 degrees, will have the same measure as the central angle, 170 degrees.
