The 7 of B♭ is A
The 7 (seven) of B♭ (B flat, Bb) is A: a major seventh above the root.
B♭ — the root, 1A — the 7
How to find it
Count letters first, the root included: B, C, D, E, F, G, A. A 7th lands on A.
Then the sound: a major seventh is 11 semitones above B♭, which is exactly where A is — no sharp or flat needed.
Where you meet it
The 7 is a half step below the root: the major seventh, the 7th of the maj7 chord and the leading tone of the key.
