Answer:
OPTION B: 162, 486, 1458
Step-by-step explanation:
The given sequence is 2, 6, 18, 54, . . .
It is a geometric sequence and the common difference is 3.
The general form of a geometric sequence is: a, ar, ar², ar³, . . .
Here a = 2 and r = 3.
term of a Geometric progression is
.
Note that the fourth term is 54.
i.e.,
.
Similarly, .
Also, .
Hence, OPTION B is the answer.
Since the measure of angle is
The measure of its reference angle =
=
Now we have to compute the value of
The value of () lies in the fourth quadrant. In fourth quadrant, the value of tan is always negative.
So,
= -1.
