Correct Answer: 42 / 42
The pattern is $n(n+1)$: $1 \times 2 = 2$, $2 \times 3 = 6$, $3 \times 4 = 12$, $4 \times 5 = 20$, $5 \times 6 = 30$, so $6 \times 7 = 42$. / प्रतिरूप $n(n+1)$ है: $1 \times 2 = 2$, $2 \times 3 = 6$, $3 \times 4 = 12$, $4 \times 5 = 20$, $5 \times 6 = 30$, अतः $6 \times 7 = 42$।
