Find the sixth term in the geometric sequence: sqrt3y^3, -3y^5, 3sqrt3y^7


Answer: -27y^13

2) Find three geometric means between -sqrt2 and -4sqrt2.

Answer: -2, 2sqrt2, -4

Thanks

    1) I agree

    2) Your answer is OK, but these are not geometric means. They are three numbers in a geometric progression. Another possible answer would be -2, -2 sqrt2, -4.
