Question

Write the first five terms of the sequence an = n - 2?

Answer 1

Answer:

-1, 0, 1, 2, 3

Step-by-step explanation:

All we need to do is substitute n for our first 5 terms:

a1 = 1 - 2 = -1

a2 = 2 - 2 = 0

a3 = 3 - 2 = 1

a4 = 4 - 2 = 2

a5 = 5 - 2 = 3

Answer 2

Answer:

-1,0,1,2,3

Step-by-step explanation:

The n is the term number

an = n-2

Let n =1     a1 = 1-2 = -1

Let n =2     a2 = 2-2 = 0

Let n =3     a3 = 3-2 = 1

Let n =4     a4 = 4-2 = 2

Let n =5     a5 = 5-2 = 3
