A town doubles its size every 17 years. If the population is currently 3,070, what will the population be in 68 years?

The town doubles its size every 17 years, so in 17 years the population will be 3,070 * 2 = <<3070*2=6140>>6140.

In 34 years, the population will be 6140 * 2 = <<6140*2=12280>>12280.
In 51 years, the population will be 12280 * 2 = <<12280*2=24560>>24560.
In 68 years, the population will be 24560 * 2 = <<24560*2=49120>>49120. Answer: \boxed{49120}.
