Answer:
Explanation:
The ratio of the first two terms is -2/6 = -1/3. Their difference is -2-6 = -8.
The ratio of the next two terms is -10/-2 = 5. Their difference is -10-(-2) = -8.
The ratio is not common, but the difference is. This is an arithmetic sequence with a common difference of -8. Its first term is 6, so the recursive formula is ...
a(1) = 6
a(n) = a(n-1) -8
