The picture shows a regular hexagon drawn to show the exterior angles. what is the measure of the angle marked l?
60 degrees
120 degrees
360 degrees
720 degrees

60

Step-by-step explanation:

You find that by finding the interior angle and subtracting that from 180. We can you the interior angle formula and find that it is 120. Subtracting that from 180 is equal to 60.

Option A is correct.

Step-by-step explanation:

Given: ;

for n = 2

=

for n =3

=

Simlarly , for n =4

=

and so on...

Common ratio(r) states that for a geometric sequence or geometric series, the common ratio is the ratio of a term to the previous term.

we have;  

Now; by recursive formula for geometric series:

where is the first term and r is the common ratio:

Substitute the value of  and  

we have;

therefore, the explicit rule for the geometric sequence is;
