Correct Answer: 423
Solution : Given: 473, 464, 448, ?, 387
Subtract the squares of the consecutive numbers (starting from 3) from each term to get the next term of the series. 473 – (3)2 = 473 – 9 = 464 464 – (4)2 = 464 – 16 = 448 448 – (5)2 = 448 – 25 = 423 423 – (6)2 = 423 – 36 = 387
So, 423 is the missing number. Hence, the third option is correct.
