Answer:

Therefore, the first three term of the sequence is:

  • [tex]a_1\:=\:-3[/tex]
  • [tex]a_2\:=\:-2[/tex]
  • [tex]a_3\:=\:-1[/tex]

Hence, the sequence is:

[tex]-3, -2, -1, ...[/tex]

Step-by-step explanation:

Given the nth term

[tex]a_{n} = n-4[/tex]

The first three terms can be obtained by putting [tex]n=1, n=2[/tex] and [tex]n=3[/tex] respectively in the given nth term

Putting [tex]n=1[/tex] to get the first term

[tex]a_1\:=\:1-4[/tex]

[tex]a_1\:=\:-3[/tex]

Putting [tex]n=2[/tex] to get the second term

[tex]a_2\:=\:2-4\:\:[/tex]

[tex]a_2\:=\:-2[/tex]

Putting [tex]n=3[/tex] to get the three term

[tex]a_3\:=\:3-4\:[/tex]

[tex]a_3\:=\:-1[/tex]

Therefore, the first three term of the sequence is:

  • [tex]a_1\:=\:-3[/tex]
  • [tex]a_2\:=\:-2[/tex]
  • [tex]a_3\:=\:-1[/tex]

Hence, the sequence is:

[tex]-3, -2, -1, ...[/tex]

Answer:

-3,-2,-1

Step-by-step explanation:

We want to find the first three terms of the sequence with n-th term.

[tex]a_n=n-4[/tex]

When n=1, we obtain:

[tex]a_1=1-4 = - 3[/tex]

When n=2, we obtain:

[tex]a_2=2-4 = - 2[/tex]

When n=3, we obtain:

[tex]a_n = 3-4 = - 1[/tex]

When n=4, we get:

[tex]a_4=4-4 = 0[/tex]

Therefore the first three terms of the sequence are:

-3,-2,-1
