The statement p q represents "If a number is doubled, the result is even." Which represents the inverse?
O -p -q where p = a number is doubled and q = the result is even
Og p where p = a number is doubled and q = the result is even
- where p = the result is even and g = a number is doubled
9 - p where p = the result is even and q = a number is doubled

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
