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

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
