Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

FORMULA

Take the absolute value of differences between counts of runs of 2 nonprimes congruent to 1 mod 4 and 3 mod 4

EXAMPLE

a(3)=3 because in A093185 the count is 33 and in A093186 the count is 36. 36-33=3.
