A098177 Start with the first n, which reads: "Prolong the sequence with n numbers having their parity opposed to n". Then read and obey the second n, then the third n, etc. This sequence is the slowest increasing one with such rule.

1, 2, 3, 5, 8, 10, 12, 14, 16, 18, 20, 22, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101, 103, 105, 107, 109, 111, 113, 115, 117, 119, 121, 123, 125, 127, 129

Table of n, a(n) for n=1..66.

Example

The first term, "1", means: "Add 1 even number to the sequence" - thus we write "2". We must now read and obey this "2": "Add 2 odd numbers to the sequence" - thus we write 3 and 5. We will then write 3 even numbers, followed by 5 even numbers (altogether 8 even numbers, thus "8" to "22"), etc.
