1,2

Terms ending in zero are not in the sequence; when reversed they produce a term with a leading zero.

Carole Dubois, Table of n, a(n) for n = 1..5001

a(7) = 17 and a(8) = 28; the addition 17 + 82 is a palindrome (99).

a(8) = 28 and a(9) = 37; the addition 28 + 73 is a palindrome (101). Etc.

Cf. A228730 (the sum of two consecutive terms is a palindrome in base 10).

Sequence in context: A124365 A115896 A116018 * A297181 A294121 A048095

Adjacent sequences: A337862 A337863 A337864 * A337866 A337867 A337868
