- Let's examine the pattern in the given series: 48, 32, 23, 19, ?

- The difference between consecutive numbers is:

- 48 to 32 gives a difference of 16

- 32 to 23 gives a difference of 9

- 23 to 19 gives a difference of 4

- Observing these differences, we notice a pattern: 16, 9, 4.

- Each difference decreases by 7 (16 - 9 = 7, then 9 - 4 = 5).

- Continuing this pattern, the next difference should decrease by 3.

- So, the next difference should be 4 - 3 = 1.

- Subtracting 1 from 19 gives 18.

Option 2: 18 is the correct answer.
