Patterns obtained from digit and iterative digit sumsof Palindromic, Repdigit and Repunit numbers, itsvariants and subsets

The digit and iterative digit sums of Palindromic numbers, their primes and squares, repdigit, repunit, their squares and cubes produced different patterns and sequences. The digit and iterative digits sum of the Palindromic, repdigits and repunit numbers are the same but with different patterns
