Comments

Same as subtracting the index (n) from the output (a(n)) in A269020.

Examples

			a(20)=4 because A269020(20) = 24, and 24-20=4.
a(5)=2, a(6)=3 and A269023(3)=8, so a(6) = 8-6+1 = 3.
		

Crossrefs

Cf. A269020, A269023.

Formula

a(n) = either a(n-1) or a(n-1)+1.

When a(n) = a(n-1)+1, a(n) = A269023(a(n)) - n + 1.
