If it takes 13 years to double the population of already 127,866, that means that it grows around 9836 people annually. 23-13 = 10, so multiply that by 9836, giving you 98,358 because thats the remaining years after the population doubles. So, 255,732, which is the doubled population after 13 years + 98,358, the population after the remaining 10 years =354,090, the population after 23 years.
