Answer:
1.) d = 2, arithmetic sequence
2.) not arithmetic neither geometric sequence
3.) r = 3, geometric sequence
Step-by-step explanation:
you will know if the sequence is arithmetic or geometric by testing the sequence whether they have common difference or common ratio.
example 1.) 3, 5, 7, 9
a1 = 3
a2 = 5
a3 = 7
try common difference:
a2 - a1 = 5 - 3 = 2
a3 - a2 = 7 - 5 = 2
as you can see they have common difference, therefore arithmetic sequence
example 2.) 5, 10, 12, 30
a1 = 5
a2 = 10
a3 = 12
try common difference:
a2 - a1 = 10 - 5 = 5
a3 - a2 = 12 - 10 = 2
therefore not common difference,
now, try common ratio
a2/a1 = 10/5 = 2
a3/a2 = 12/10 = 1.2
therefore not common ratio
5, 10, 12, 30 is not geometric neither arithmetic sequence.
example no.3) 2, 6, 18, 54
a1 = 2
a2 = 6
a3 = 18
now, try common ratio
a2/a1 = 6/2 = 3
a3/a2 = 18/6 = 3
common ratio, therefore geometric sequence
