Question

The number of members in the fourth generation of a family tree is .

• A. four
• B. eight
• C. sixteen

Answer 1

The correct option is C sixteen

The number of members in each generation is double the member in the previous generation.

So, starting from the current generation (1 member),
First generation $=1\times 2=2$
Second generation $=2\times 2=4$
Third generation $=4\times 2=8$
Fourth generation $=8\times 2=16$
