What is the common ratio of the geometric sequence below? –2, 4, –8, 16, –32, ...
SOVA2 [1]

Answer:

The common ratio of the geometric sequence is:

r=-2

Step-by-step explanation:

A geometric sequence has a constant ratio 'r' and is defined by

a_n=a_1\cdot r^{n-1}

where

  • aₙ is the nth term
  • a₁ is the first term
  • r is the common ratio

Given the sequence

-2,\:4,-8,\:16,\:-32,\:...

Compute the ratios of all the adjacent terms:  r=\frac{a_n+1}{a_n}

\frac{4}{-2}=-2,\:\quad \frac{-8}{4}=-2,\:\quad \frac{16}{-8}=-2,\:\quad \frac{-32}{16}=-2

The ratio of all the adjacent terms is the same and equal to

r=-2

Therefore, the common ratio of the geometric sequence is:

  • r=-2

Prove that sin20 sin40 sin60 sin80=3/16
xeze [42]
Sin 20° · sin 40° · sin 80° = 1/2 ( cos 20° - cos 60° ) · sin 80° =
= 1/2 ( cos 20° sin 80° - cos 60° sin 80° ) =
= 1/2 ( (sin 100° + sin 60°)/2 - 1/2 sin 80° )=            ( sin 100° = sin 80° )
= 1/2 · ( 1/2 sin 60° ) = 1/4 sin 60° = √3 / 8
sin 60° = √ 3/2
√ 3 / 2 · √ 3 / 8 = 3/16  ( correct )
