2.3.5.6.7.8.9.10 four addition formulas of eight sequences are equal to 10.11.12.13 respectively, but each number can only be used once,

2.3.5.6.7.8.9.10 four addition formulas of eight sequences are equal to 10.11.12.13 respectively, but each number can only be used once,

It's impossible. 2 + 3 + 5 + 6 + 7 + 8 + 9 + 10 = 50
And 10 + 11 + 12 + 13 = 46
The two are not equal. It is impossible to make four equations with each number only once
