Step-by-step explanation:
There are 4! = 24 poosible permutations of the four letters. Let the letters be A, B, C and D. Two permutations will have only letter A in the correct envelope, two more permutations will have only letter B in the correct envelope, two more will have only letter C in the correct envelope and two more will have only letter D in the correct envelope. Therefore 8 out of the 24 possible permutations will have only one letter with the correct address. The required probability is 8/24 = 1/3.

Step-by-step explanation:
It can work to see what sequence each defines:
A) -8, -1, 6, ...
B) -15, -8, -1, ...
C) -22, -15, -8, ...
D) -22, -15, -8, ... . . . . matches C
E) -29, -22, -15, ...
The two that define the same sequence are ...
C) f(x) = 7x -29
D) a1 = -22, a(n+1) = an +7
