## anonymous one year ago HELP!! Determine and state if the sequence below is Arithmetic or Geometric. Then find the value of the term. 4,-8, 16, -32... Find a10

1. anonymous

-8-4=-12,16-(-8)=24 So it is not arithmetic $\frac{ -8 }{ 4 }=-2,\frac{ 16 }{ -8 }=-2$ so c.r. is same calculate a10

2. anonymous

okay so what is A10?|dw:1433808187123:dw|

3. anonymous

$a_{n}=ar ^{n-1}$ a=4 r=-2 n=10 find $a _{10}$
