If $5 + 3 = 16$ and $7 + 4 = 33$, then $6 + 2 = ?$

1. 32
2. 14
3. 16
4. 18

Correct answer: 32

Solution

The pattern is $a + b = a^2 - b$ or equivalently a custom operation based on the first number. For $5 + 3$, $5^2 - 9 = 16$ and for $7 + 4$, $7^2 - 16 = 33$; the intended pattern here is $a^2 - b^2$? But matching the given examples, the consistent rule is $a^2 - b^2 + b$? Using the standard SSC-style intended pattern, $6 + 2 = 36 - 4 = 32$.
