An arithmetic sequence would have a common difference between successive terms, not the case here.
A geometric sequence has a common ratio; let's check:



That's a common ratio of 3 so as far as we can tell a geometric sequence.
Answer: geometric
The answer to the first part is (4,1).
The answer to the second part is (11,2).
Answer:
37.6
Step-by-step explanation:
Answer: $467.21
Step-by-step explanation:
8% of 600 = 48
600 - 48 = 552
8% of 552 = 44.16
552 - 44.16 = 507.84
8% of 507.84 = 40.6272
8% of 507.84 ≈ 40.63
507.84 - 40.63 = 467.21
Point slope equation for point (h,k) and slope m is given by
y-k=m(x-h)
compare given equation with formula
we get h=-7, k=3
so the required point is (-7,3)
