 OFFSET 0,1 COMMENTS This square root of 2 in the 17-adic field ends with digit 6. The other, A322562, ends with digit 11 (B when written as a 17-adic number). LINKS Seiichi Manyama, Table of n, a(n) for n = 0..10000 Wikipedia, p-adic number FORMULA a(n) = (A322559(n+1) - A322559(n))/17^n. For n > 0, a(n) = 16 - A322562(n). Equals A309989*A322566 = A309990*A322565. EXAMPLE The solution to x^2 == 2 (mod 17^4) such that x == 6 (mod 17) is x == 43594 (mod 17^4), and 43594 is written as 8EE6 in heptadecimal, so the first four terms are 6, 14, 14 and 8. PROG (PARI) a(n) = truncate(sqrt(2+O(17^(n+1))))\17^n CROSSREFS Cf. A322559, A322560. Digits of 17-adic square roots: A309989, A309990 (sqrt(-1)); this sequence, A322562 (sqrt(2)); A322565, A322566 (sqrt(-2)).
