According to a certain rule, a sequence of numbers is: half, minus two fifths, three tenths, minus four seventeen, twenty

1/2,-2/5,3/10,-4/17,
an=(-1)^(n+1)*n/(n^2+1)
The following is
5/26

The number of columns arranged according to a certain rule is: 1 2,1 3,1 10,1 15,1 26,1 35… The seventh number in this column is () A. 1 Forty-five B. 1 Forty C. 1 Forty-six D. 1 Fifty

Molecular Law: molecule is constant 1;
The rule of denominator: the denominator of the first number is: 12 + 1 = 2,
The denominator of the second number is: 22-1 = 3,
The denominator of the third number is: 32 + 1 = 10,
The denominator of the fourth number is: 42-1 = 15,
The denominator of the fifth number is: 52 + 1 = 26,
The denominator of the sixth number is: 62-1 = 35,
The denominator of the seventh number is: 72 + 1 = 50,
...
The denominator of the odd number is N2 + 1,
The denominator of the even term is n2-1,
So the seventh number is one
50.
Therefore, D
