In the following question, select the missing number from the given series.
60, 53, 47, 42, 38, ?

Let's look at the difference between consecutive terms:
60−53=7

53−47=6

47−42=5

42−38=4

The difference reduces by 1 each time: 7,6,5,4,…
Following this trend, the next difference should be 3:

Missing number=38−3=35
