Answer:

[tex]a_5=-12[/tex]

Step-by-step explanation:

Given that,

The first term of the sequence, a = 8

Common difference, d = -5

We need to find the fifth term of the sequence.

The nth term of the sequence is given by :

[tex]a_n=a+(n-1)d[/tex]

Put n = 5, a = 8 and d = -5 in the above formula

[tex]a_5=8+(5-1)(-5)\\\\=8+4(-5)\\\\=8-20\\\\=-12[/tex]

So, the fifth term of the sequence is -12.
