Refer to the following series and answer the question (counting to be done from left to right only): (Left) 3 7 9 8 5 3 6 2 2 1 5 3 7 1 5 7 5 7 1 8 4 3 6 9 7 4 4 (Right) How many such odd digits are there, each of which is immediately preceded by an odd digit and also immediately followed by an odd digit?

Refer to the given series and answer the question that follows (counting to be done from left to right only): (Left) 6 6 8 6 7 4 5 9 9 1 7 6 8 1 4 5 4 7 1 4 1 1 4 3 5 4 3 (Right) How many such even numbers are there, each of which is immediately preceded by an odd number and also immediately followed by an even number?

This question is based on the five three-digit numbers given below. (Left) 238 745 324 523 872 (Right) (For example, take 697 - the first digit = 6, the second digit = 9, and the third digit = 7.) Note: All operations must be performed from left to right. What will be the result if the third digit of the largest number and the second digit of the smallest number are added?
