There is a column of numbers: 2, 1, 1, 2. The rule is: from the second number, three times of each number is equal to the sum of the two numbers before and after it Can the 1000th number be divided by 2? How many times is the 1000th number divided by 3?

The remainder of 2 is 0,1,1,0,1,1,0,1,1,1
1000÷3=333.1
therefore
The 1000th number can be divided by two if it is divided by two
The remainder of dividing by 3 is: 2,1,1,2,2,1,1,2,2
2,1,1,2 cycles, so
1000÷4=250.0
therefore
The 1000th number is divided by 3 to make 2
