# What are the first four terms of the sequence represented by the expression n(n - 1) - 5

**Solution: **

Given expression: n(n - 1) - 5

Let us have a_{n} = n(n - 1) - 5

The first four terms of the sequence: a_{1 }, a_{2 }, a_{3}, a_{4}

Let us take n = 1, 2, 3, 4 to find the first four terms.

First Term: a_{1} =1(1 - 1) - 5 = -5

Second term:a_{2} = 2(2 - 1) - 5 = -3

Third Term: a_{3 }=_{ } 3(3 - 1) - 5 = 1

Fourth Term:a_{4 }= 4(4 - 1) - 5 = 7

Thus the first four terms are:

-5, -3, 1, 7

# What are the first four terms of the sequence represented by the expression n(n - 1) - 5

**Summary: **

The first four terms of the sequence represented by the expression n(n - 1) - 5 are -5, -3, 1, 7
