Answer:
Answer is below
Step-by-step explanation:
Subtract 16 from both sides.
Divide both sides by -8
The formula is a subscript n = 6^n
Where a1 is the first term and d is the common difference of the sequence
Thus, the first term is 6, second term 36, then 216.....
thus the sequence is, 6, 36, 216, .....................
Therefore, this is a geometric sequence with a common difference of 6
