Answer:
Tn = 6.4 + 1.8n
Step-by-step explanation:
Given
Sequence: 8.2, 10, 11.8, 13.6
Required
The formula of the sequence.
First, the type of the sequence needs to be determined (arithmetic or geometric)
It is an arithmetic sequence because each successive sequence is separated by a common difference..
The common difference is represented by d and it's calculated as follows.
d = 10 - 8.2 or 11.8 - 10 or 13.6 - 11.8
Each of the above gives
d = 1.8
Now, that we have the common difference; the next is to determine the formula using the Arithmetic Progression formula.
Tn = T1 + (n - 1)d
Where T1 is the first term of the progression; T1 = 8.2
By substituting 8.2 for T1 and 1.8 for d.
This gives
Tn = 8.2 + (n - 1) * 1.8
Open bracket
Tn = 8.2 + 1.8 * n - 1 * 1.8
Tn = 8.2 + 1.8n - 1.8
Collect like terms
Tn = 8.2 - 1.8 + 1.8n
Tn = 6.4 + 1.8n
Hence, the formula of the sequence is Tn = 6.4 + 1.8n
Alexander is correct. He uses P=2(l+w)
The answer is 5/15.
Here is why:
So we know that the sum has to be greater than or equal to 8/15.
When adding 1/15 to 2/15 you get 3/15 which is less than 8/15 so it’s not the answer. Then 8/30 = 4/15. 4/15+2/15=6/15 which is less than 8/15 so it’s not the answer. Thirdly, 5/15+2/15= 7/15 which is less than 8/15 so it’s not the answer. Lastly, 8/15+2/15= 10/15 which is larger than 8/15 so it is greater than 1/2 so it is the answer. The answer is d
