Use Mathematical Induction to Prove the Given Statement for All $$1 \cdot 4 + 2 \cdot 7 + 3 \cdot 10 + \ldots + n ( 3 n + 1 ) = n ( n + 1 ) ^ { 2 }$$

Short Answer

Use mathematical induction to prove the given statement for all positive integers n.
- $$1 \cdot 4 + 2 \cdot 7 + 3 \cdot 10 + \ldots + n ( 3 n + 1 ) = n ( n + 1 ) ^ { 2 }$$
