Backward Difference
The backward difference is a Finite Difference defined by
 | (1) |
 |  |  | (2) |
|  | ||
|  | (3) |
In general,
 | (4) |
is a Binomial Coefficient.Newton's Backward Difference Formula expresses 
as the sum of the 
th backward differences
 | (5) |
is the first th difference computed from the difference table.See also Adams' Method,Difference Equation, Divided Difference, Finite Difference, Forward Difference,Newton's Backward Difference Formula, Reciprocal Difference
