What should come in place of ‘?’ in the given series?
32 52 68 80 88 ?

The correct answer is 92 (Option 4).

To find the missing number represented by ‘?’, let us analyze the pattern or differences between consecutive numbers in the series:

$52-32=20$
$68-52=16$
$80-68=12$
$88-80=8$

Observing the differences between consecutive terms (20, 16, 12, 8), we can see that each successive difference decreases by 4:

$20-4=16$
$16-4=12$
$12-4=8$

Following this pattern, the next difference should be:

$8-4=4$

To find the value of ‘?’, we add this difference to the last known term in the series (88):

$?=88+4=92$

Therefore, the number that comes in place of ‘?’ is 92.
