6.000,7.000,.857,8.168,.105,77.790
Which of the following responses completes the series
.001
740.857
9.524
.013
The answer is
.001
Because:
The (n+2)-th number is the 3-decimal-place approximation of the ratio of the n-th to the (n+1)-th
Indeed:
$6/7 \approx 0.857$
$7/0.857 \approx 8.168$
$0.857/8.168 \approx 0.105$
$8.168/0.105 \approx 77.790$
And then:
$0.105/77.790 \approx 0.001$
