Question

I am having trouble with question 6 part b and c because I don’t understand what they mean by the "nth".

nwe have the answer for part (a) as 2.7(7 + 1) or 112.
b. What is the greatest 3-digit number in this pattern?
c. What is the greatest number in this pattern that is less
than 104?
d. If this pattern was produced in a normal spreadsheet,
what is the number in cell A14?
6. The first windmill has 5 matchstick
squares,
the second has
9, and the third has 13, as shown. How many matchsticlk
squares are in (a) the 10th windmill? (b) the nth windmil?
(c) How many matchsticks will it take to build the nth
windmill
ric.
