Which number will follow next in the given number series?
25,24,22,19,15,10,?
- A8
- B7
- C4
- D9
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
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
