Assuming the recursive definition is tn = 2*tn-1
t1 = 3
t2 = 2*t1 = 2*3 = 6
t3 = 2*t2 = 2*6 = 12
t4 = 2*t3 = 2*12 = 24
They are 14, 42, 126, 378 and 1134.
A descending geometric sequence is a sequence in which the ratio between successive terms is a positive constant which is less than 1.

Ratio
Yes, that's what a geometric sequence is about.
They are 14, 42, 126, 378 and 1134.
A descending geometric sequence is a sequence in which the ratio between successive terms is a positive constant which is less than 1.
yes
a, ar, ar^2 and ar^3 where a and r are constants.
A static sequence: for example a geometric sequence with common ratio = 1.
FALSE (Apex)
No, they do not. If the first term is negative, they always decrease.

Ratio
It is 4374
The difference between succeeding terms in a sequence is called the common difference in an arithmetic sequence, and the common ratio in a geometric sequence.
