Find an explicit rule for the nth term of a geometric sequence where the second and fifth terms are -6 and 162, respectively. Pl

kicyunya [14]

Hello,

$u_{0} =a\\
 u_{1} =a*r\\
 u_{2} =a*r^{2}=-6\\
 u_{3} =a*r^{3}\\
 u_{4} =a*r^{4}\\
 u_{5} =a*r^{5}=162\\
....\\
\boxed{ u_{n} =a*r^{n}} \\

\dfrac{ 162}{-6} = \dfrac{ u_{5} }{ u_{3}} = \dfrac{ a*r^{5}}{ a*r^{2}} =r^3= -27\\
==\ \textgreater \ r=-3\\

 u_{2} =a*r^{2}=-6=a*(-3)^2 \ ==\ \textgreater \ a=-\frac{6}{9} =-\frac{2}{3}\\


\boxed{ u_{n} =-\frac{2}{3}*(-3)^{n}=(-1)^{n+1}*2*3^{n-1}} \\

Please help guys.......<br>equation practice

nignag [31]

Answer:

Step-by-step explanation:

m∠AOC = 180 as it is straight line

m∠AOC = m∠AOB + m∠BOC

m∠AOB + m∠BOC = 180

3x + 124 + 6x + 29 = 180

9x + 153 = 180

9x = 180 - 153

9x = 27

x = 27/9

x = 3

m∠BOC = 6x +29 = 6*3 + 29 = 18 +29 = 47
