Question

B₄ =128; q=-1/2; n=10​

Answer 1

Ответ:

- 1024

Объяснение:

$b_{4}= b_{1}*q^{3}\\\\128=b_{1}*(-\frac{1}{2} )^{3}\\\\128=b_{1}*(-\frac{1}{8} )\\\\b_{1}=128:(-\frac{1}{8})\\\\b_{1}=-1024$

Answer 2

It seems like you've provided some variables, but you haven't specified what you want to do with them. B₄ = 128 is presumably a value, and q = -1/2 and n = 10 are also values for the variables q and n.

If you have a specific question or task related to these variables, please provide more context or details so I can assist you accordingly.
