Please help!! Thank you :)

(a). | b - a | = a - b

Step-by-step explanation:

If a > b, then

(a). b - a < 0 ⇒ - ( b - a ) = a - b (true)

(b). > 0 for some "a" and "b" is true

(c). > 0 is true for some "a" and "b"

(d). | | < 0 (false)

(e). | | > 1 (true if b ≠ 0)

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9
