what are the next 2 numbers in this sequence: 20 , 1 ,18 ,4 ,9 ,1
The sequence consists of triangular numbers, which can be calculated using the formula ( T_n = \frac{n(n + 1)}{2} ). The numbers in the sequence correspond to ( T_1, T_3, T_5, T_6, T_7, T_8, T_9 ) respectively. Following this pattern, the next number is ( T_{10} = \frac{10(10 + 1)}{2} = 55 ). Therefore, the next number in the sequence is 72.
This is a peculiar number sequence which follows the following rule: +7, -4, +8, -3, +9, -2... The next few functions would be +10, -1, +11, -0 And thus the next few numbers in the sequence would be 17+10=27, 27-1=26, and so on. The sequence in total goes 2, 9, 5, 13, 10, 19, 17, 27, 26, 37, 37.

The sequence consists of triangular numbers, which can be calculated using the formula ( T_n = \frac{n(n + 1)}{2} ). The numbers in the sequence correspond to ( T_1, T_3, T_5, T_6, T_7, T_8, T_9 ) respectively. Following this pattern, the next number is ( T_{10} = \frac{10(10 + 1)}{2} = 55 ). Therefore, the next number in the sequence is 72.
The next number in the sequence would be 23. The sequence consists of prime numbers.
The difference between the numbers is increasing by 2 every time. Therefore, 18 + 9.5 = 27.5 is the next number in the sequence.
The rule is: "To get the next term, double this term and subtract 2."(66 x 2) - 2 = 130 comes next
1+10 - 2 (2 is one less than 3, the next answer in the sequence) = 9. 10 + 3 - 8 (8 is one less than 9) = 5 3 + 9 - 4 = 8 etc...; so the next two numbers in the sequence will be 11 and 5.
This is a peculiar number sequence which follows the following rule: +7, -4, +8, -3, +9, -2... The next few functions would be +10, -1, +11, -0 And thus the next few numbers in the sequence would be 17+10=27, 27-1=26, and so on. The sequence in total goes 2, 9, 5, 13, 10, 19, 17, 27, 26, 37, 37.
The next number in the sequence is 27.
