Correct Answer: 97
Each term is twice the previous term minus one: $7 = 4 \times 2 - 1$, $13 = 7 \times 2 - 1$, $25 = 13 \times 2 - 1$, $49 = 25 \times 2 - 1$. Hence the next term is $49 \times 2 - 1 = 97$. / प्रत्येक पद पिछले पद के दोगुने में से एक घटाने पर मिलता है: $7 = 4 \times 2 - 1$, $13 = 7 \times 2 - 1$, $25 = 13 \times 2 - 1$, $49 = 25 \times 2 - 1$। अतः अगला पद $49 \times 2 - 1 = 97$ होगा।
