The pattern of odd numbers
Difference is 5,7,9,11,13 Second difference is 2 (2x)^2 gives 4,9,16,25 Difference between 2x^2 and sequence is -5 Thus, the nth term will be (2n)^2-5
The difference between -20 and 13 is calculated by subtracting 13 from -20. This results in -20 - 13, which equals -33. Therefore, the difference is -33, indicating that -20 is 33 units less than 13 on the number line.
37, this sequence counts up from 5 the difference between 2 and 7. the difference between 20 and 28 is 8 making the next number 9, and 28 and 9 = 37.
The sequence 6, 13, 20, 27 increases by 7 each time. This indicates it is an arithmetic sequence with a common difference of 7. The nth term can be expressed as ( a_n = 6 + 7(n-1) ), which simplifies to ( a_n = 7n - 1 ). Thus, the nth term is ( 7n - 1 ).
To complete the sequence 5, 10, 3, 15, 20, 13, 25, 30, we can look for patterns. The first set of numbers (5, 10, 15, 20, 25, 30) increases by 5, while the second set (3, 13) appears to increase by 10. The next logical number in the pattern would be 35, following the sequence of increasing by 5. However, if we are looking for a continuation of the second set, the next number would be 23 (13 + 10).

20
yes it is
70 - (20 - 13)
37, 47, 58, 70, ... Each time the difference in the sequence increases by 1. From 2 to 7, we increase by 5 From 7 to 13, we increase by 6 From 13 to 20, we increase by 7 From 20 to 28, we increase by 8 From 28 to 37, we increase by 9, etc..
13 + 7 = 20 13 - 7 = 6
It's, 7n+6
