A linear pattern.
They are 13 and 19 which are prime numbers
The spacing is 6 1+6=7 7+6=13 13+6=19 19+6=25 so the missing number in the sequence is 13
19
13
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
prime numbers
To find the pattern, simply look for the difference in the first two numbers, then the following pair of numbers, etc. 2 9 5 13 10 19 17 2 + 7 = 9 9 - 4 = 5 5 + 8 = 13 13 - 3 = 10 10 + 9 = 19 19 - 2 = 17 The pattern is +7, -4, +8, -3, +9, -2...
They are 13 and 19 which are prime numbers
13 and 19 are prime. 33 and 45 are composite.
Yes 13/19 is rational because any number that can be expressed as a fraction is a rational number
The teenage years are 13-19. This is because they have "teen" at the end of the number.
The spacing is 6 1+6=7 7+6=13 13+6=19 19+6=25 so the missing number in the sequence is 13
19
13
What would be the next number in this series 15 12 13 10 11 8?
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
They are: 11, 13, 17 and 19
