Make denomenators the same
common denom is 2n²
multiply 3/2n by n/n
mulitply 1/n² by 2/2
we get

combine fractions

multiply both sides by 2n²
2n+2=n-2
minus n both sides
n+2=-2
minus 2 both sides
n=-4
A.) {4,.8,.16,.032,...}
Begin with 4 and multiply by 0.2, the ratio, to obtain successive term.
360in^3
