Question

B3=-3,b6=-81 найдите пятый член геометрический прогрессии​

Answer 1

Решение:

B6=B3*q²[6-3]

-81=-3 * q²3

q²3 =81/3

q²3 = 27

q = 3

Вn=B[n-1] *q

B4=B3*q

B4=-3*3=-9

B5=B4*q

B5= - 9*3= -27

Вn=B1*q²[n-1]

Answer 2

To find the fifth term of a geometric progression, we need to know either the common ratio or the first term. Unfortunately, you have only provided the values of B3 and B6, which are the third and sixth terms, respectively.

Without additional information, we cannot determine the common ratio or the first term of the geometric progression. Please provide either the common ratio or the first term, and I will be happy to help you find the fifth term.
