$180$ / $180$
3.
$182$ / $182$
4.
$188$ / $188$
Correct Answer: $185$ / $185$
Each term is obtained by doubling the previous term and adding $1, 2, 3, 4, 5$ in order: $4 \times 2 + 1 = 9$, $9 \times 2 + 2 = 20$, $20 \times 2 + 3 = 43$, $43 \times 2 + 4 = 90$, so the next term is $90 \times 2 + 5 = 185$. / प्रत्येक पद पिछले पद को दोगुना करके क्रमशः $1, 2, 3, 4, 5$ जोड़ने पर प्राप्त होता है: $4 \times 2 + 1 = 9$, $9 \times 2 + 2 = 20$, $20 \times 2 + 3 = 43$, $43 \times 2 + 4 = 90$, अतः अगला पद $90 \times 2 + 5 = 185$ होगा।
