SUMMARY
The rᵗʰ term in the nᵗʰ row of Pascal's triangle is definitively represented by the binomial coefficient nCr, calculated using the formula n!/r!(n-r)!. The discussion emphasizes the use of mathematical induction as a robust method to prove this relationship. Participants suggest starting with the base case of (x + y)^1 and assuming the formula holds for (x + y)^n to demonstrate its validity for (x + y)^(n+1). This approach effectively utilizes the properties of Pascal's triangle, particularly the summation of adjacent entries.
