Question

B={x/xeN,100<2*x-3<200}

Answer 1

B={53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101}

Answer 2

100<2*x-3<200 / +3
103<2*x<203 / :2
103/2 < x < 203/2
=> B=(103/2 , 203/2)
     B ∈ N
=> B={52, 53, 54, ...., 100, 101}
