Question

Whats the the first three sequence of n-4

Answer 1

Answer:

-3,-2,-1

Step-by-step explanation:

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

$a_n=n-4$

When n=1, we obtain:

$a_1=1-4 = - 3$

When n=2, we obtain:

$a_2=2-4 = - 2$

When n=3, we obtain:

$a_n = 3-4 = - 1$

When n=4, we get:

$a_4=4-4 = 0$

Therefore the first three terms of the sequence are:

-3,-2,-1

Answer 2

Answer:

Therefore, the first three term of the sequence is:

• $a_1\:=\:-3$

• $a_2\:=\:-2$

• $a_3\:=\:-1$

Hence, the sequence is:

$-3, -2, -1, ...$

Step-by-step explanation:

Given the nth term

$a_{n} = n-4$

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

Putting $n=1$ to get the first term

$a_1\:=\:1-4$

$a_1\:=\:-3$

Putting $n=2$ to get the second term

$a_2\:=\:2-4\:\:$

$a_2\:=\:-2$

Putting $n=3$ to get the three term

$a_3\:=\:3-4\:$

$a_3\:=\:-1$

Therefore, the first three term of the sequence is:

• $a_1\:=\:-3$

• $a_2\:=\:-2$

• $a_3\:=\:-1$

Hence, the sequence is:

$-3, -2, -1, ...$
