Answer:
geometric sequence
Step-by-step explanation:
The terms of the sequence have a common ratio of -12/3 = -4, so the sequence is geometric. The general term is ...
an = 3(-4)^(n-1)
so the sum can be written as ...

(Note the summation starts at n=0, corresponding to a first term of 3.)
Answer:
A) 40
Step-by-step explanation:
The sum of the interior angles of a regular polygon is:

For a hexagon, we put n=6

Let x be the 6th interior angle, then



The largest interior angle is 140°
Therefore the least exterior angle will be:

The correct choice is A
Answer:
This ans is easily solved by using algebraic identities a²- b² = (a+b) (a-b)
Step-by-step explanation:
1. convert into Identity
2. solve quadratic equation that formed.
