To find our answer, we can substitute the values given into the equation and then simplify it.
a_n is not given, as it is the value of the nth term.
a_1 is given, as it is the first term: -10
n is not given.
d is given, as it is the common difference: 4
a_n = -10 + 4(n - 1)
a_n = -10 + 4n - 4
a_n = 4n - 14
Our answer is 4n - 14.
