Jadhav Theorem/Examples/Square of 102

Examples of Use of Jadhav Theorem
Consider the square of $102$.

Consider $102$ as a term in an arithmetic sequence:
 * $100$, $102$, $104$

whose common difference is $2$.

Then from the Jadhav Theorem:
 * $102^2 - 100 \times 104 = 2^2$

from which we have:
 * $102^2 = 100 \times 104 + 4 = 10404$
