Let us denote the smaller even integer by

.
Then, the next even integer must be

.
To verify, set

as any even number, say

.
Then, the next even integer must be 2 more than this number, i.e.

.
The sum of these two consecutive even integers can be expressed as:

We are told that this sum divided by four is 189.5, i.e.

Multiplying both sides by 4 will reverse the division:

Subtracting 2 from each side will reverse the addition:

Dividing both sides by 2 will reverse the multiplication:

Therefore, the two consecutive integers must be
378 and
380.

Answer:
2.
Step-by-step explanation:
The common difference is 5 so the first number is 7 - 5 = 2.
