Answer:
→The number that logan is thinking about =Rational Number
→If you will take opposite of Rational number = Negative Rational Number
→The two numbers are inverses of each other, which we call additive inverse, which means sum of Positive Rational Number plus Negative rational Number will equal to Zero.
→The number he is thinking about will be also a rational number and it's decimal expansion will be either non terminating repeating or Decimal expansion will terminate.
→Modulus of both the number will be same.That is
| Positive Rational number|= Positive Rational number
| Negative Rational number |= Positive Rational number
Each number will be equidistant from origin.
