The time the difference between two decimals is an integer is when the decimal value is the same for both numbers. For example, 1.20 - 0.20 = 1. 1.20 and 0.20 are decimals while 1 is an integer. 0.20 is the decimal value while 1 is the whole number.
 
        
                    
             
        
        
        
The series converges, and its sum is 1/2.
If r > 1, the series is divergent.  If r < 1, the series is convergent.  In our sequence, r, the common ratio we multiply by to get the next term, is 7/9; therefore it is convergent.
To find the sum of a convergent series, we use the formula
a/(1-r), where a is the first term and r is the common ratio.  We then have
1/9÷(1-7/9) = 1/9÷2/9 = 1/9×9/2 = 1/2
