Answer:
r = 2
Step-by-step explanation:
nth term of a geometric sequence = .
Where,
a = first term, r = common ratio,
We are given that, the 11th term is 32 times larger than the 6th term of the geometric sequence. Thus:
the 6th term can be expressed as
The 11th term is expressed as
Since the 11th term is 32 times larger than the 6th term, therefore, the following equation can be derived to find the common ratio, r, of the sequence:
, therefore:
Divide both sides by ar⁵
Common ratio = 2
Answer:
228
Step-by-step explanation:
19 times 12 =228
Answer:
Step-by-step explanation:
Since the sequence is increasing by a constant factor () each time, we know that this is an arithmetic sequence.
The formula for an arithmetic sequence is the following:
Where is the number in the sequence and is the constant that the sequence is increasing by.
Based on all of the information given, we know that (since is the first number in the sequence), and , so we can construct the formula:
Yes. As an example, (-5)-(-5) = -5+5=0
