Sequences
The below QuickQuestion Interface © generates 10 random questions on sequences.
Choose which types of sequences you want to include in the questions (Linear, Quadratic, Cubic or Geometric).
Decide if you want a negative first coefficient (for linear that means descending sequences, quadratic and cubic means a<0 and for geometric it means the sequence will oscilate).
Choose the type of question you would like to appear.
If you want simple examples, then it will either have a constant or a single coefficient.
Finally choose how big you want the coefficients to be.
When typing answers, lists should be separated by commas, powers are written with ^ (ie n^2 is n squared), nth term should use the letter n, and for geometric sequences, the nth term is of the form a x b^(n1).
Type the answer in the answer boxes, and check your answers.

Ideas for Teachers
This is a good alternative to the QQI activity, if you just want to put 10 questions on the board. Then you can get answers from students to enter in the boxes before checking them, and correcting as necessary.
However, the real power in this activity is when you get the students using it themselves. In a computer lesson, set them all going on the activity, and get them to repeat until they get every question correct.
Or you can set it as a homework, telling them the conditions to use (different conditions for different students to differentiate the homework). Then get them to do one or two sets, all correct, and to take a screen shot and either email it to you, or, even better, stick it in their books. Since the questions are random, every student will get a different set of questions, and the immediate feedback means they can go back and correct their work straight away.
