A)
942

B)
997

C)
919

D)
950


Correct Answer :

997


Explanation :

The patteren is 5³ – 3 , 6³ – 3, 7³ – 3, 8³ – 3 , 9³ – 3, 10³ – 3,....
i.e, 5³ – 3 = 125 – 3 = 122
6³ – 3 = 216 – 3 = 213
7³ – 3 = 343 – 3 = 340
8³ – 3 = 512 – 3 = 509
9³ – 3 = 729 – 3 = 726
10³ – 3 = 1000 – 3 = 997
So, the missing number is 997.

C)
1457

D)
1542


Correct Answer :

1457


Explanation :

The patteren of the series
82 + (25 * 1² ) = 82 + 25 = 107
107+ (25 * 2²) = 107 + 100 = 207
207 + (25 * 3²) = 207 + 225 = 432
432 + (25 * 4²) = 432 + 400 = 832
832 + ( 25 * 5² ) = 832 + 625 = 1457
So, the missing number is 1457.

A)
224

B)
244

C)
242

D)
218


Correct Answer :

244


Explanation :

Each number in the series is 2 less than thrice the preceding number.
i.e, (4 * 3) – 2 = 12 – 2 = 10
(10 * 3) – 2 =30 – 2 = 28
( 28 * 3) – 2 = 84 – 2 = 82
( 82 * 3) – 2 = 246 – 2 = 244
( 244 * 3) – 2 = 732 – 2 = 730
So, the missing number is 244.
