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.

The sequence appears to be decreasing with varying intervals: 50 to 33 (17), 33 to 25 (8), 25 to 20 (5), 20 to 17 (3), 17 to 14 (3), 14 to 13 (1), and 13 to 11 (2). The differences between the numbers suggest that the next number decreases by 1 from 11, resulting in 10. Therefore, the next number in the sequence is 10.
1 x 5 = 5 5 x 10 = 50 ; 10 is 5+5 50 x 20 = 1000; 20 is 10+10 1000 x 40 = 40,000 ; 40 is 20 + 20 40,000 x 80 = 3,200,000; 80 is 40+40 therefore the next 2 numbers are 40,000 and 3,200,000

25 is the next number that appears in that sequence.
The sequence given is formed by the triangular numbers, which are obtained by adding consecutive integers. The next number in the sequence after 20 can be calculated by adding 6 (the next integer after 5, which was added to get 15 to 20). Therefore, the next number is 20 + 6 = 26. So, the next number is 26.

Therefore, the next number in the sequence is 72.

The sequence appears to be increasing at a variable rate. The pattern seems to be adding 1, then 3, then 5, then 10. Following this pattern, the next number in the sequence would be 20 + 15, which equals 35.
Could be 26 again: 16 = 3*5+1 26 = 5*5+1 21 = 4*5+1 31 = 6*5+1 so I thought the sequence could be n*(5+1) and the sequence of n: 3,5,4,6,5,7,6,8,... add two subtract one etc. Simpler put it could be 10+6, 20+6, 10+11, 20+11, the next answer being 10+16 -26.
The rule is 5 10 15 20 25 30 .... etc and accordingly the next number in the sequence will be 106
