Answer:
0.3188646
Step-by-step explanation:
an=a×r^n-1
a6=0.6×0.9^5
=0.354294
1st swing: 0.6
2nd swing: 0.9×0.6=0.54
3rd swing: 0.9×0.54= 0.486
4th 0.9×0.486= 0.4374
5th 0.9×0.4374= 0.39366
6th 0.9×0.39366=0.354294

<span>the line over the 28 means the 28 repeats forever.
1.282828.... and so on
let x be the rational number 1.28...
we can use this trick:
100*1.282828....= 128.282828... (the decimal 28 part repeats)
100x = 128.28...
next:
100x - x = 128.282828... - 1.282828...
the .282828... part will be subtracted away
99x = 127
divide both sides by 99 to get
x= 127/99</span>
