Consider the following sequence of numbers: 5 1 4 7 3 9 8 5 7 2 6 3 1 5 8 6 3 8 5 2 2 4 3 4 9 6 How many odd numbers are followed by the odd number in the above sequence?

To solve this, we apply the 'Systematic Linear Scanning' method [78]. We need to find pairs where an **Odd number** is immediately **followed by** another **Odd number**. First, recall the odd digits: 1, 3, 5, 7, 9.
