I am preparing myself for the Entrance Exams so I need help.

1. The middle number of 5 odd numbers is 297. What is the last number?
297
-->-----|-----|-----|-----|-----|-----<--
* Number line*

2. If there is a 10% service change in a restaurant, what is the service charge payable on a bill of €17.50?

3. What is the next term: 4, 3.9, 3.7, 3.4, ___?
4. One and one half metres of cloth costs n€2.40. How much is this per metre?

The best preparation for these exams is for you to do these problems yourself. We'll be glad to check them for you.
