Answer:
The next number in the series = 5039
Step-by-step explanation:
The series is given to be : 1, 5, 23, 119, 719, .....
1 is obtained by :
2! - 1 = 2 - 1
= 1
5 is obtained by :
3! - 1 = 6 - 1
= 5
23 is obtained by :
4! - 1 = 24 - 1
= 23
119 is obtained by :
5! - 1 = 120 - 1
= 119
719 is obtained by :
6! - 1 = 720 - 1
= 719
Similarly, The next number will be obtained by : 7! - 1
So, The next number in the series = 5040 - 1
= 5039
