Pn=1/3pn-1 and p4=108 , then p6= ? please show steps
Natali5045456 [20]
p_n=\dfrac13p_{n-1}
\implies p_n=\dfrac13\left(\dfrac13p_{n-2}\right)=\dfrac1{3^2}p_{n-2}
\implies p_n=\dfrac13\left(\dfrac13p_{n-3}\right)=\dfrac1{3^3}p_{n-3}

and so on, up to

p_n=\dfrac1{3^{n-4}}p_4=\dfrac{108}{3^{n-4}}

which means

p_6=\dfrac{108}{3^{6-4}}=\dfrac{108}9=12

A student skipped a step when she tried to convert 15 hours to seconds,and she got the following incorrect result ?
Gelneren [198K]
She did not convert 1 minute into 60 seconds. and 15 hours in seconds.
she did it like this:
15min ×60 seconds/1 min
900 seconds.
The SI unit of time is second so she should have converted the hours and minutes into seconds first and then start the calculation.
