Q20:

Which of the following geometric sequences can be summed up to infinity?

Q21:

What is the minimum number of terms should be taken from the geometric sequence 4 1 , 8 2 , 1 6 4 , starting from the first term to make the sum greater than 4,456?

Q22:

Q24:

The figure shows the steps to producing a curve 𝐶 . It starts as the boundary of the unit square in Figure (a). In Figure (b), we remove a square quarter of the area of the square in (a). In Figure (c), we add a square quarter of the area that we removed in (b). In Figure (d), we remove a square quarter of the area of the square we added in (c). If we continue to do this indefinitely, we will get the curve 𝐶 . We let 𝑅 be the region enclosed by 𝐶 . By summing a suitable infinite series, find the area of region 𝑅 . Give your answer as a fraction.

Q25:
