Determine whether the sequence is a geometric sequence. Explain

Hello:

the sequence is a geometric sequence : An+1=q*An q : is a common ratio

or : q=An+1/An

ex01:

the sequence 3, 6, 12, 24, 48 is a geometric sequence because:

48/24=24/12=12/6=6/3=2 (common ratio : q)

ex02:

the sequence : An = 5*3^n is a geometric sequence because:

An+1 = 5*3^ (n+1)

= 5*3^n * 3

= 3 * (5*3^n)

An+1 = 3*An (common ratio : q = 3)
