Answer:
C.)-12
Step-by-step explanation:
A sequence is an ordered list of numbers.
One way to define the sequence is by listing the numbers of the sequence.
This list is
a1,a2,a3,a4,a5, ... ,an
Where a1 is the first number of the sequence, a2 is the second number of the sequence , ... , an is the ''nth'' number of the sequence meaning that the sequence has a total of ''n'' numbers.
In this exercise, the sequence is
-4,-2,-12,-14,...
This means that the first number of the sequence is -4 ⇒ a1 = -4
The second number is -2 ⇒ a2 = -2
The third number is -12 ⇒ a3 = -12
The value of a3 in the sequence is -12
The correct option is C.)-12
