Correct Answer: 158

Each term is double the previous plus two: $3 \times 2+2=8$, $8 \times 2+2=18$, $18 \times 2+2=38$, $38 \times 2+2=78$, so $78 \times 2+2=158$. / प्रत्येक पद पिछले का दोगुना जमा दो है: $3 \times 2+2=8$, $8 \times 2+2=18$, $18 \times 2+2=38$, $38 \times 2+2=78$, अतः $78 \times 2+2=158$।
