Question 1: The Iirst 5 terms of a quadratic sequence are: 4, 10, 18, 28, 40 Work out the difference between the 10th and 20th terms. 2: Below are patterns of tiles. The number of tiles in each form quadratic sequences. Find the number of tiles in pattern n for each.
What is a quadratic nth term? A quadratic nth term is a rule used to generate a sequence based on the square numbers and has the general form an^{2}+bn+c where a, b, and c are constants (a constant is a number that does not change).
Here are the first five terms of a different quadratic sequence. 12 20 (b) Find an expression, in terms of n, for the nth term of this sequence. (2) The nth term of a sequence is given by an2 + bn where a and b are integers. The 2nd term of the sequence is —2 The 4th term of the sequence is 12 (a) Find the 6th term of the sequence.
