Let $$S(K)$$ $$ = 1 + 3 + 5... + \left( {2K - 1} \right) = 3 + {K^2}.$$ Then which of the following is true

Principle of mathematical induction can be used to prove the formula

$$S\left( K \right) \Rightarrow S\left( {K + 1} \right)$$

$$S\left( K \right) \ne S\left( {K + 1} \right)$$

$$S\left( 1 \right)$$ is correct
