24,21,17,10,-1, what is the next number for this series?
Answers
Answer:
the next number will be -14
Concept: A series in mathematics is essentially a description of the process of successively adding an infinite number of quantities to a specified initial quantity. A significant component of calculus and its generalisation, mathematical analysis, is the study of series.
Given: the series 24, 21, 17, 10, -1
To find: the next number in the series
Solution: 24 - 3 = 21 ( difference between 24 and 21 is 3)
21 - 4 = 17 ( difference between 21 and 17 is 4)
17 - (3 + 4) = 17 - 7 = 10 ( difference between 17 and 10 is the sum of 3 and 4.
10 - (7 + 4) = 10 - 11 = -1 ( difference between 10 and -1 is the sum of 7 and 4.
-1 - (11 + 7) = -1 - 18 = -19 ( difference between -1 and -19 is the sum of 11 and 7.
Therefore,
The next number for the series will be -19.
