6 7 9 5 6 9 7 6 8 7 6 7 8 6 9 4 6 7 7 6 9 5 7 6 3
Count each 7 which is not immediately preceded by 5 but is immediately followed by either 2 or 3. How many such 7's are there ?
5 7 2 6 5 7 3 8 3 7 3 2 5 7 2 7 3 4 8 2 6 7 8
How many 3's are there in the following sequence which are neither preceded by 6 nor immediately followed by 9 ?
9 3 6 6 3 9 5 9 3 7 8 9 1 6 3 9 6 3 9
Which is the third number to the left of the number which is exactly in the middle of the following sequence of numbers ?
1 2 3 4 5 6 7 8 9 2 4 6 8 9 7 5 3 1 9 8 7 6 5 4 3 2 1
There are 27 numbers in the given sequence.
So. middle number = 14th number = 9.
Clearly, the third number to the left of this 9 is 4.
