I think you have read the question wrong. Go back to source and you might see that you have to chose the correct answer from one of 19 , 36, 49, or 50. There should be another sequence of numbers leading up to 64. Hint, think squares
49
7
10
34, 58, 56, 60, ?
18
Next number will be.. 19.
6
The next prime after 19 is 23
20 is the next number greater than 19. The next prime number greater than 19 is 23.
35- 4= 31-4= 27-4= 23-4= 19-4= 15-4= 11-4= 7,3,-1....
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.
59 is the next number in this series.
