a(1)=1, a(n) is the smallest integer > a(n-1) such that a(n) is even if k(n)=1, a(n) is odd if k(n)=2, where k(n) denotes the n-th term of the Kolakoski sequence (A000002).

FORMULA
| a(n) is conjectured to be asymptotic to 4/3*n.
|
|
|
EXAMPLE
| Kolakoski sequence begins: 1,2,2,1,1,2,1, ....from the rule, a(2) > a(1)=1 and even, so a(2)=2. a(3)>a(2)=2 and even, so a(3)=4. a(4)>a(3)=4 and odd so a(4)=5...
