A. 7/20

Step-by-step explanation:

Simplify the following:

(-7)/10×(-1)/2

(-7)/10×(-1)/2 = (-7 (-1))/(10×2):

(-7 (-1))/(10×2)

10×2 = 20:

(-7 (-1))/20

-7 (-1) = 7:

7/20

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
