Question

Помогите пж даю 40 баллов Якщо знаменник геометричної прогресії дорівнює 1/2 , а другий член дорівнює 8, то перший член послідовності дорівнює​

Answer 1

Ответ:

$16$

Объяснение:

$q=\frac{1}{2}; b2=8; b2=b1*q; b1=\frac{b2}{q}\\ b1=\frac{8}{\frac{1}{2} }=16$

Answer 2

Geometric Progression Calculation

To find the first term of a geometric progression when the common ratio and the second term are given, we can use the formula:

First Term (a) = Second Term (b) / Common Ratio (r)

Given: - Common ratio (r) = 1/2 - Second term (b) = 8

Using the formula, we can calculate the first term: First Term (a) = 8 / (1/2)

This simplifies to: First Term (a) = 8 * 2 First Term (a) = 16

Therefore, the first term of the geometric progression is 16.
