Which number will follow next in the given number series?
25,24,22,19,15,10,?

  1. A
    8
  2. B
    7
  3. C
    4
  4. D
    9

Solution & Step-by-step Explanation

Let's find the difference between consecutive numbers in the series:
24−25=−1
22−24=−2
19−22=−3
15−19=−4
10−15=−5
The differences form a sequence of consecutive negative integers: −1,−2,−3,−4,−5.
Following this pattern, the next difference must be −6.

Therefore, the next term is:

10−6=4
