n^2-n+11 work out the first three terms

To find the first three terms of the sequence represented by n^2-n+11, we simply plug in the first three values of n:

When n=1: 1^2-1+11 = 11
When n=2: 2^2-2+11 = 11
When n=3: 3^2-3+11 = 13

Therefore, the first three terms of the sequence are 11, 11, and 13.
