If we consider the series;
582+23=605 ----> 1st term
605-17=588 ----> 2nd term
588+23=611 ----> 3rd term
611-17=594 ----> (which is not 4th term) so instead of 634, it should be 594.
582+23=605 ----> 1st term
605-17=588 ----> 2nd term
588+23=611 ----> 3rd term
611-17=594 ----> (which is not 4th term) so instead of 634, it should be 594.

If we add 6 to every alternate number the alternate number comes same except 600.
Eg- 582 (1st number) +6 = 588 (3rd number).
605 (2nd number) +6=611 (4th number).
Eg- 582 (1st number) +6 = 588 (3rd number).
605 (2nd number) +6=611 (4th number).

There is two series of alternate numbers, we can separate it like:
582, 605, 588, 611, 634, 617, 600
1). 582, 588, 634, 600
2). 605, 611, 617
In each number, we add 6 we get next number, ex- 582+6= 588, 588+6= 594, 594+6=600, So here in series it is given 634 instead of 594. So odd number is (634) answer.
582, 605, 588, 611, 634, 617, 600
1). 582, 588, 634, 600
2). 605, 611, 617
In each number, we add 6 we get next number, ex- 582+6= 588, 588+6= 594, 594+6=600, So here in series it is given 634 instead of 594. So odd number is (634) answer.

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.
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.

Answer 617 only prime number in the given series.

I agree with answer.

One of the obvious reasons I think is that 617 is prime and all others are composite. Why didn't anybody see this? It is I suppose a stronger reason than simple adding and subtracting.
