Consider the sequence of consecutive even numbers starting from 0, arranged in a staggered format, where each row contains one more number than the previous row. The beginning of this arrangement is shown below: $0$ $2\; 4$ $6\;\underline{8}\;10$ $12\: 14\: 16\: 18$ $20\: 22 \: 24 \: 26\: 28 $ The number in the middle of the third row is 8. What is the number in the middle of the 101-st row?
