Correct Answer: 121
Solution : Given: 1, 25, ?, 361, 841, 1681
Add the square root of the previous number to a consecutive even number starting from 4 and then square the resultant, to get the next number in the series – (1)2 = 1; (1 + 4)2 = (5)2 = 25; (5 + 6)2 = (11)2 = 121; (11 + 8)2 = (19)2 = 361; (19 + 10)2 = (29)2 = 841; (29 + 12)2 = (41)2 = 1681
So, the required number is 121. Hence, the fourth option is correct.
