In the ancient Chinese mathematical classic "Suanfa Tongzong," many mathematical problems are presented in the form of poems. One of these poems can be adapted as follows: "Among five brothers—A, B, C, D, E—they owe a thousand wen for wine. Brother A tells Brother B, 'I will pay back three hundred. The difference turns out to be just over ten wen. How much should each person pay?'" This indicates that five brothers owe a thousand wen for wine, and the amounts they pay back form an arithmetic sequence, with Brother A paying back three hundred. In this problem, how much should Brother D pay back?
