How many such even numbers are there in the following number sequence, each of which is immediately followed by an odd number and immediately preceded by an even number? 4 8 7 6 8 9 5 6 9 5 7 8 4 6 9 5 5 8 8 6 7 7 9 

How many such even numbers are there in the following number sequence, each of which is immediately followed by an odd number and immediately preceded by an even number? 4 8 7 6 8 9 5 6 9 5 7 8 4 6 9 5 5 8 8 6 7 7 9  Correct Answer Four

Left 4 8 7 6 8 9 5 6 9 5 7 8 4 6 9 5 5 8 8 6 7 7 9 Right

Even numbers that are immediately followed by an odd number and immediately preceded by an even number:

(4 8 7) (6 8 9) 5 6 9 5 7 8 (4 6 9) 5 5 8 (8 6 7) 7 9

So, there are four even numbers that are immediately followed by an odd number and immediately preceded by an even number

Hence, "Four" is the correct answer.

There are two rows, each containing 3 numbers. Below are some rules to be used to get the resultant number for each row separately. Use the rule from left to right for each row and find the answer to the question. Rule: 1. If an even number is followed by an even number, then the first number will be subtracted from the second. 2. If an odd number is followed by an odd number, then both will be added. 3. If an odd number is followed by an even number, then the even number will be subtracted from the square of the odd number. 4. If an even number is followed by an odd number, then the odd number will be subtracted from the even number.
