Question

Find four geometric means between 25 and 800.

Answer 1

\(\normalsize\color{blue}{ 25 \times r^5=800}\) (you have to "jump"/"move" 5 times since knowing that you have FOUR missing means, 25 is the first term, and 800 is the 6th term.

Answer 2

so,
\(\normalsize\color{blue}{ 25 \times r^5=800}\)
\(\normalsize\color{blue}{ r^5=800 \div 25}\)
\(\normalsize\color{blue}{ r^5=32}\)
\(\normalsize\color{blue}{ r^5=2^5}\)
\(\normalsize\color{blue}{ r=2}\)

Answer 3

ok thanks
