Question

B3=-18 b5=-162 S5=? q=?

Answer 1

b3 = -18

b1 = -2

b5 = -162

b4 = -sqrt(-18*-162)= -54

bn = bn-1 * q

q = bn / bn-1 = b5 / b4 = 162 / 54 = 3

S5 = (-162 * 3 + 2) / 2 = -242

Answer 2

To determine the values of S5 and q, we need more information or context about the sequence or pattern being used. The given values B3 and B5 seem to represent elements of a sequence or series, but the specific pattern governing their relationship is not evident from the provided data.

If you can provide more terms of the sequence or the pattern used to generate the sequence, I would be able to calculate the values of S5 and q accordingly. Additionally, please clarify what S5 and q represent in the context of the sequence.
