Answer:
B and C and D
Step-by-step explanation:
The true statement is that: if you cannot get from one term to the next by adding or multiplying by a constant value, the sequence is neither arithmetic nor geometric
<h3>How to determine the true statement</h3>
A progression can either be arithmetic, geometric or neither.
- When the progression has a common difference (gotten by addition), then the progression is arithmetic
- When the progression has a common ratio (gotten by multiplication), then the progression is geometric
If the above are not true, then the sequence is neither arithmetic nor geometric

Answer:
(8a)⁻¹⁸
1 / (8a)¹⁸
Step-by-step explanation:
(((8a)^6a)^4/4a))^-3
((8a)^6a*4/4a)^-3
((8a)^6)^-3
(8a)^6*(-3)
(8a)⁻¹⁸
1 / (8a)¹⁸
