- 6; 6; 9; 15;... are the first four terms of a quadratic number pattern.
- The following sequence is a combination of an arithmetic and a geometric sequence: 4;4;10;12;16;36;...
- 2, x and y are the first three terms of a an arithmetic sequence. If each term is decreased by 1, the resulting sequence is geometric. Find the two sequences.
- The first three terms of an arithmetic sequence are 2x - 4; x - 3 and 8 - 2x. Determine the value of x and hence the sum of the first 41 terms.
- In a particular sequence, the 1st term is 3⁄2 and the 4th term is -12
- The 11th term of an arithmetic sequence is 32 and the sum of the first 11 terms is 187. Calculate the 21st term of the sequence.
- Given the following quadratic sequence: -2; 0; 3; 7;...
- Given the finite arithmetic sequence: 5; 1; -3; ...; -83; -87
