Yes the initial offset is incorrect, but there is more wrong with this 
sequence,
particularly, a(3) = 2 and a(18) = 9 are incorrect.  Indexed from 0, the 
sequence
should start

-4 -2 -1 -2 0 1 3 2 3 5 7 5 6 5 6 8 9 8 10 11 14 12 13 12 14 15 17 16 17
19 24 22 23 22 24 25 27 26 27 29 35 33 34 33 35 36 38 37 38 40 45 43 44
43 45 46 48 47 48 50 55 53 54 53 55 56 58 57 58 60 63 61 62 61 63 64 66
