Answer:
Yes, its geometric
r = 2
Step-by-step explanation:
GP : 4, 8, 16, 32, .....
Let the term be denoted by " t ".
t1 = 4
t2 = 8
t3 = 16
t4 = 32
Let the common difference be " r ".
r1 = t2 / t1
= 8 / 4
r1 = 2
r2 = t3 / t2
= 16 / 8
r2 = 2
r3 = t4 / t3
= 32 / 16
r3 = 2
Since, the common differences are same,
r = 2
and,
the given sequence is geometric.
