Hey guys why can't we found another reasoning. Like I came out with an answer 600 as it is only one divisble by 100 leaving no remainder.

600 +17
617 +17
634 -23
611 -23
588 +17
605 +17
582
If we consider, +17 added twice then -23, it makes sence so 582 should be the answer

Seperates the patterns like this
582, 588, ?, 600.
605, 611, 617.

In each pattern add +6 and then;
588 + 6 = 594.
594 + 6 = 600.

582-605=23,
605-588=17
588-611=23
634-617=17
611-634=23

So balance 17 +17 =34
Add balance no is 600 +34 =634 ans.

I think 600 is the correct answer because 617+23 = 640 should come if they do it alternatively.

582+23=605.
605-17=588.
588+23=611.
611-17=594 => 634 is wrong answer.
594+23=617.
617-17=600.

Because all number are composite number except 617 (which is prime number).

582+6 = 588.
605+6 = 611.
588+6 = 594(but the given answer is 634).
611+6 = 617.
594+6 = 600.
