question is...

insert two G.M between 2 and 16

Answer 1

a1=2 a2 a3=16

a3 a2
-- =--- =q=ratio
a2 a1

put a1,a3 into it
to find a2

Answer 2

16 a2
-- = -- now find a2=geometric mean
a2 2

Answer 3

that gives you 1 GM.

to find 2 GMs, we do somthing like this :
\(\Large \dfrac{2}{x}=\dfrac{x}{y}=\dfrac{y}{16}\)
find x and y which are your GMs
