How can you determine the difference between an arithmetic and geometric sequence if you are given the first 4 terms of the sequ
Bess [88]
Compute successive differences of the terms.

If they are all the same, the sequence is arithmetic and the common difference is the difference you have found.

If successive pairs of differences have the same ratio, the sequence is geometric and the common ratio is the ratio you have determined.


Example of arithmetic sequence:
  1, 3, 5, 7
Successive differences are 3-1 = 2, 5-3 = 2, 7-5 = 2. All the differences are 2, which is the common difference of the sequence.

Example of geometric sequence:
  1, -3, 9, -27
Successive differences are -3-1 = -4, 9-(-3) = 12, -27-9 = -36. These are not the same, so the sequence is not arithmetic. Ratios of successive pairs of differences are 12/-4 = -3, -36/12 = -3. These are the same, so the sequence is geometric with common ratio -3.

100 POINTS!! Express in radical form.
Vilka [71]

Answer:

27   4th root (x^3)

Step-by-step explanation:

(81x) ^ 3/4

We know (ab) ^c = a^c b^c

81 ^ (3/4)  * x^3/4

We can rewrite 81 as 3^4

(3^4)^(3/4)  * x^3/4

We know that a^b^c = a^ (b*c)

3^(4*3/4)  * x^3/4

3^(3) * x^3/4

27  * x^3/4

27   4th root (x^3)
