As, 841= (29) ²
Similarly, 289 = (17)²

Correct Answer: (3, 21, 24)

Explanation:

In each set
2nd number = 1st number x 7
and 3rd number = 1st number x 8
Let us see
As, 14 = 2 x 7
and 16 = 2 x 8
Similarly, 21 = 3 x 7
and 24 = 3 x 8

Correct Answer: (18, 30, 42)

Explanation:

In (12, 20, 28), every next number is obtained by adding 8 with the previous number and similarly, in (18, 30, 42).

Correct Answer: (29, 41, 43)

Explanation:

Set of consecutive odd prime numbers.

Correct Answer: (554, 655, 756)

Explanation:

In each set
2nd number = 1st number + 10-1
3rd number = 2nd number + 101
Let use see
As, 223 + 101 = 324
and 324 + 101 = 425
Similarly, 554 + 101 = 655
and 655 + 101 = 756

Correct Answer: 1728

Explanation:

As, F = 6 ? 6³=216
Similarly, L = 12 &rArr: (12) ³=1728
Therefore = 1728

Correct Answer: 378

Explanation:

As, sum of digits of 584 = 5 + 8 + 4 = 17
and sum of digits of 488 = 4 + 8 + 8 = 20
Similarly, sum of digits of 294 = 2 + 9 + 4 =15
? Sum of digits of 378 = 3 + 7 + 8 = 18
Here, difference of both are (20 - 17 ) = ( 18 - 15 ) = 3
Therefore ? = 378 is an answer.
