Which of the following indicates the first step of mathematical induction
for the mathematical statement $n + 1 > n$?
🎥 Video solution / Text Solution of this question is given below:
R includes $(1,1), (2,2), (3,3)$ → Reflexive.
Check symmetry: $(1,2)$ exists but $(2,1)$ does not → Not symmetric.
Check transitivity: $(1,2)$ and $(2,2)$ imply $(1,2)$ already → transitive holds.
Hence, relation is reflexive and transitive but not symmetric.
