Directions (61-65) : Find the wrong number in following number series.

17 , 22 , 32, 47 , 67, 93, 122

The correct option is 93.

Let us analyze the pattern of the given number series by examining the difference between consecutive terms:

$22-17=5$

$32-22=10$

$47-32=15$

$67-47=20$

Notice that the differences between consecutive terms form an arithmetic progression increasing by 5 each time: 5, 10, 15, 20, ...

Following this pattern, the next difference should be 25.

Adding 25 to 67 gives:

$67+25=92$

Let us check the subsequent term using the next difference, which should be 30:

$92+30=122$

This matches the last term in the series (122). Therefore, the number 93 is wrong and should be replaced by 92.
