Answer:
Infinite series equals 4/5
Step-by-step explanation:
Notice that the series can be written as a combination of two geometric series, that can be found independently:

The first one:  is a geometric sequence of first term (
 is a geometric sequence of first term ( ) "1" and common ratio (r) "
) "1" and common ratio (r) "  ", so since the common ratio is smaller than one, we can find an answer for the infinite addition of its terms, given by:
 ", so since the common ratio is smaller than one, we can find an answer for the infinite addition of its terms, given by: 
The second one:  is a geometric sequence of first term "1", and common ratio (r) "
 is a geometric sequence of first term "1", and common ratio (r) "  ". Again, since the common ratio is smaller than one, we can find its infinite sum:
 ". Again, since the common ratio is smaller than one, we can find its infinite sum:

now we simply combine the results making sure we do the indicated difference: Infinite total sum=
