Question

should Geoff expect in the sixth year?

64 bulbs

512 bulbs

128 bulbs

256 bulbs

Answer 1

Geoff's garden is doubling the number of bulbs each year, so in the fourth year, he would expect 64 bulbs (32 x 2). In the fifth year, he would expect 128 bulbs (64 x 2). Therefore, in the sixth year, he would expect 256 bulbs (128 x 2). The answer is 256 bulbs.
