What comes next 10 7 11 12 9 13 14?

The sequence alternates between two patterns: one decreasing by 3 and the other increasing by 1. Following this pattern, the next number after 14 would be 11 (14 - 3). Then, the number after that would be 15 (11 + 1). Thus, the next two numbers are 11 and 15.


What is the next two patterns of 2 5 10 17?

Each successive number after 2, is formed by adding 3, then 5, then 7, and so on. 2 + 3 =, 5 5 + 5 = 10 10 + 7 = 17 So the next two numbers are : 17 + 9 = 26 26 + 11 = 37 The formula for the series is n2 + 1 So when n = 1, n2 + 1 = 2 When n = 5, n2 + 1 = 26 When n = 6, n2 + 1 = 37..........and so on

What are the next two numbers in this sequence 7282445?

The sequence appears to be formed by alternating between two patterns: the first number increases by 1 (7 to 8, then 8 to 9), while the second number decreases by 1 (2 to 2, 4 to 4, and 4 to 5). Following this pattern, the next two numbers would be 6 and 6, completing the sequence as 7282445. Thus, the next two numbers are 6 and 6.


What is binary in number system?

It is a number system that uses the digits 0 and 1 only. So 0 is written 0 and 1 is 1, but two in base 10 is written 10 in binary. The first digit is 20 or 1, the next is 21 or 2, the next digits is 22 This keeps going and any number can be written in binary or base two.


What is the next number 2 9 5 13 10 19 17?

The answer is 27.The pattern is this: 2 (+7) 9 (-4) 5 (+8) 13 (-3) 10 (+9) 19 (-2) 17 (+10) 27 (-1) 26 and so on. Notice the two patterns (+7, +8, +9, +10, etc.) and (-4, -3, -2, -1, etc.) that show up when you look at the differences between each pair of numbers in the series.


What is the next sequence 7 21 8 72 9?

The sequence appears to alternate between two patterns. The first pattern consists of multiplying the previous number by 3 (7 to 21), and the second pattern involves simply increasing the last number by 1 (8 to 9). Following this logic, after 9, the next number should be (9 \times 8 = 72), leading us to conclude that the next number in the sequence is 10, which would continue the pattern. Thus, the next number is 10.
