what are the first four terms of the sequence represented by the expression n(n - 1) - 4

1 answer

The first four terms of the sequence represented by the expression n(n-1) - 4 are:

n = 1: 1(1 - 1) - 4 = -4

n = 2: 2(2 - 1) - 4 = -2

n = 3: 3(3 - 1) - 4 = 4

n = 4: 4(4 - 1) - 4 = 12

Therefore, the first four terms of the sequence are -4, -2, 4, and 12.
