Question

Identify a geometric progression.

• A. $1,3,5,7,\mathrm{9.....}$
• B. $2,4,6,8,\mathrm{10.....}$
• C. $4,8,16,32,\mathrm{64....}$
• D. $1,-1,3,-2,4$

Answer 1

The correct option is C $4,8,16,32,\mathrm{64....}$

For a G.P., the ratio must be common throughout.

Thus the sequence $4,8,16,32,\mathrm{64....}$ is a geometric progression because the common ratio is $2.$
