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.
Answer:
7 + 4
Step-by-step explanation:
note that ×
= a
Given
(2 + )² = (2 +
)(2 +
)
Each term in the second factor is multiplied by each term in the first factor, that is
2(2 + ) +
(2 +
) ← distribute both parenthesis
= 4 + 2 + 2
+ 3 ← collect like terms
= 7 + 4
This is what the graph would look like
