Answer:
.
Step-by-step explanation:
We need to find the factors of given equation;
Solution:
On Solving the above equation we get;
Now First we will take common factor from first 2 terms which is we get;
Now we will take the common factor from the last 2 terms which is 3 we get;
Here we get 2 terms in which is common factor.
Hence After factorizing the given equation we get .
Answer:
The explicit form is
Step-by-step explanation:
The explicit form of a geometric sequence is given by:
where an is the nth term, a is the first term of the sequence and r is the common ratio.
In this case:
a=162
The value of the common ratio is obtained by dividing one term by the previous term.
For the first and second terms:
108/162=2/3
For the second and third terms (In order to prove that 2/3 is the common ratio)
72/108=2/3
Therefore:
r=2/3
Replacing a and r in the formula:
The right answer is 118.
