Respuesta :

[tex] a_{n} = +(n-1)d [/tex]

We are given the first term and the common difference.

So,

[tex]a_{1}=-10 \\ \\ d=5[/tex]

Using these values in the given equation, we get:

[tex] a_{n} =-10+(n-1)*5 \\ \\ a_{n} = -10 + 5n - 5 \\ \\ a_{n} = 5n -15[/tex]

So, option C gives the correct answer.
