A340348 Add the two terms of the first pair of integers to produce b(1); add the two terms of the second pair of integers to produce b(2); add the two terms of the third pair of integers to produce b(3), etc. This sequence and the b(n) sequence share the same succession of digits. 1

3 + 24 = 27
4 + 28 = 32
5 + 39 = 44
6 + 22 = 28
8 + 45 = 53; etc.
