The squares

Each term is obtained by adding the next odd number to the previous term, as shown in the illustration.

The first 50 terms (starting from n=1) are:

1 4 9 16 25 36 49 64 81 100 121 144 169 196 225 256 289 324 361 400 441 484 529 576 625 676 729 784 841 900 961 1024 1089 1156 1225 1296 1369 1444 1521 1600 1681 1764 1849 1936 2025 2116 2209 2304 2401 2500

Example

To get the value for n=11:

  • Square the number, giving 121.

So the result is 121.
