2,_,20,29,_what is the answer ​

The missing terms are 11 and 38, and this is an example of arithmetic sequence. We got the common difference by subtracting 29 and 20. 29 - 20 = 92, _, 20, 29, _ +9 +9 +9 +92 + 9 = 1111 + 9 = 2020 + 9 = 2929 + 9 = 38We can check if the answer is correct by subtracting each number from right to left.11 - 2 = 920 - 11 = 929 - 20 = 938 - 29 = 9So, the correct ordered list is 2, 11, 20, 29, 38By subtracting 29 and 20, we can also do another checking by writing the general rule of this arithmetic sequence. First, subtract the first term which is 2 from 9 which is the common difference. 2 - 9 = -7The subtrahend (9) and the difference (-7) General rule: 9n - 79(1) - 7 = 29(2) - 7 = 119(3) - 7 = 209(4) - 7 = 299(5) - 7 = 38
