OEIS Sequences

a(n) = 56·n² + 1. A158660

Recamán's Fibonacci variation : a(1)=a(2)=1 then a(n) = a(n-1)+a(n-2)-F(n) if that number is >0 and not already in the sequence; a(n) = a(n-1)+a(n-2)+F(n) otherwise where F(n) denotes the n-th Fibonacci number. A91484

Fibonacci sequence (A000045) mod 10 with carry. A64737
