Correct Answer: 449
Solution :
Given:
15, 48, 148, ?, 1353
Multiply the number by 3 and add a natural number in increasing order starting from 3, to get the required missing number –
15 × 3 + 3 = 45 + 3 = 48
48 × 3 + 4 = 144 + 4 = 148
148 × 3 + 5 = 444 + 5 = 449
449 × 3 + 6 = 1347 + 6 = 1353
So, the required missing number in the series is 449. Hence, the third option is correct.
