(3x) •(8) =(8-1) •(5) multiply the numerator of the 1st fraction by the denominator of the second fraction.
Answer:
x = 121
Step-by-step explanation:
all angles sum = 540
87 + 92 + 105 + 135 = 419
540 - 419 = 121
Answer:
The third choice

Step-by-step explanation:
Given:
The sequence is:

To find:
The explicit formula for the given sequence and then find the 16th term.
Solution:
We have,

The ratio between two consecutive terms are:



The given sequence has a common ratio. So, the given sequence is a geometric sequence with first term 6 and common ratio
.
The explicit formula of a geometric sequence is:

Where, a is the first term and r is the common ratio.
Putting
in the above formula, we get

We need to find the 16th term. So, put
in the above formula.




Therefore, the explicit formula for the given sequence is
and 16th term of the given sequence is
.
