Week 2 – Geometric Sequences

This week, I’ve learned about geometric questions involving percentages. Although other questions in this week’s assignments were not the hardest, I managed to plow through all of them (somehow), except this one question:

P.41, Q.14: “Between the Canadian censuses in 2001 and 2006, the number of people who could converse in Cree had increased by 7%. In 2006, 87 285 people could converse in Cree. Assume the 5-year increase continues to be 7%. Estimate to the nearest hundred how many people will be able to converse in Cree in 2031.”

Man do I hate words. At first, I thought the question wanted me to calculate the sum (of said sequence), and of course, I messed up because I was confused on what was the first term. When I read through the samples questions before the real assignment questions begin, and then I made up the final equation: (note that the answer is corrected to the nearest hundred)

So there you have it 🙂
