31. Determine whether the sequence 7, 21, 35, 49 is geometric. If so, find its common ratio.

a. no

b. yes, common ratio of 14

c. yes, common ratio of 12

I'm stuck between A and B..

32. What are the next three terms of the geometric sequence 5, 15, 45,...?

135, 405, 1215? Not sure about this...

33. What is the area of a square with the dimension of 1 + sqrt of 2?

9.64?

35. Simplify: 2 sqrt of 4 + 2 sqrt of 8

4+ 5.65?

Thanks

32. Correct

33. Not sure

35. 2sqrt4+2sqrt8=4+4sqrt2
