We know that a triangle has 3 sides right?
Well, if the perimeter is 39 and there are 3 sides you would divide 39 by the 3 sides
39/3=13
Therefore, one side of the triangle would equal 13

The explicit formula is an= 4.2* .
The correct option is (b)
<h3>What is explicit formula?</h3>The explicit formula for a geometric sequence is of the form an = a1r-1, where r is the common ratio.
Given sequence: {4.2, 3.57, 3.0345, 2.5793, …}
General formula
an=4.2*
an= 4.2*
Hence, an= 4.2*
