Understanding the Context
Understanding the Pattern: What is a ‘One Less’ and a ‘One More’ in Numbers?
Breaking it down:
- One less than a multiple of 17 means: x + 1 is divisible by 17.
- One more than a multiple of 19 means: x – 1 is divisible by 19.
So the number must satisfy:
x + 1 ≡ 0 (mod 17) → x ≡ –1 (mod 17)
x – 1 ≡ 0 (mod 19) → x ≡ 1 (mod 19)
