For a finite sequence of nonzero integers, the consecutiveness of the sequences is defined by the number of pairs of consecutive terms of the sequence for which the positive difference between the two consecutive terms is 1. What is the consecutiveness for the sequence {1,4,5,6,−3,−4} ?
(A) One
(B) Two
(C) Three
(D) Four
(E) Five
Kudos for the right solution and explanation

The answer should be (B) not (C) please explain
isnt the answer two because
pair 1 : {4,5}
pair 2 : {5,6}
no other pair seems to fulfill the condition of sequences can any one help?

In a sequence of 6 numbers, there are 5 sets of adjacent terms (1 and 4, 4 and 5, etc.). Check each one to see how many are consecutive:
1 and 4: no.
4 and 5: yes
5 and 6: yes
6 and -3: no
-3 and -4: yes
That’s a total of 3, choice (C)
1 and 4: no.
4 and 5: yes
5 and 6: yes
6 and -3: no
-3 and -4: yes
That’s a total of 3, choice (C)
