Correct Answer: 42 / 42
The successive differences are $4, 6, 8, 10$, increasing by 2 each time, so the next difference is $12$ and $30 + 12 = 42$ (the terms are $n(n+1)$ for $n = 1$ to $6$). / क्रमागत अंतर $4, 6, 8, 10$ हैं, प्रत्येक बार 2 बढ़ते हुए, अतः अगला अंतर $12$ और $30 + 12 = 42$ (पद $n = 1$ से $6$ हेतु $n(n+1)$ हैं)।
