Each part equals -19. 0-19=-19, 4-23=-19,...so 25-X=-19. This means 25+19=X, so the missing number is 25+19 which is 44.

To find the next number in the series 16, 23, 19, 19, 22, 15, 25, we can look for a pattern among the numbers. The differences between consecutive numbers are +7, -4, 0, +3, -7, +10. The next difference appears to be -6, which would lead to the next number being 25 - 6 = 19. Therefore, the next number in the series is 19.
15 is composite number 17, 19 and 23 are prime numbers.
17, 19, 23, 29, and 31
15 has more than exactly two factors (1, 3, 5, and 15), therefore it is composite. 17, 19, and 23 each have exactly 2 factors (1 and the number itself), so they are primes.

The mean = The sum of all the values ÷ The number of values. 18 + 15 + 22 + 18 + 25 + 19 + 23 = 140 : Number of values = 7 Mean = 140 ÷ 7 = 20
13 x 23 x 19 x 15 = 85215
35- 4= 31-4= 27-4= 23-4= 19-4= 15-4= 11-4= 7,3,-1....
