Answer:
-7,-5.8,-4.6,-3.4,-2.2
Step-by-step explanation:
A geometric sequence must have a common ratio.
-3 / 1 = -3
9 / -3 = -3
-27 / 9 = -3
81 / -27 = -3
The first sequence is a geometric sequence.
-5.8 / -7 = 0.829...
-4.6 / -5.8 = 0.793...
The second sequence is not a geometric sequence (it is an arithmetic sequence with a common difference of 1.2).

Answer:
2³·3²·x·y²
Step-by-step explanation:
Unique prime factors are 2, 3, x, y. Each of those is raised to a power to obtain the given expression.
72xy² = 8·9·x·y² = 2³·3²·x·y²
Do you know how to solve it because I can't see the problem
