Answer:
d) geometric; r = 4
Step-by-step explanation:
Differences of adjacent terms are not constant (they are 1.2, 4.8, 19.2, ...), so the sequence is NOT ARITHMETIC.
Ratios of adjacent terms are constant (they are 1.6/0.4 = 6.4/1.6 = 25.6/6.4 = 4), so the sequence is geometric with a common ratio of 4.
Should be tan positive 30
