Write the first five terms of the sequence.(Assume that n begins with 1.) $a _ { n } = - n - 2$
A)-3, -2, -3, -4, -5
B)-2, -3, -4, -5, -6
C)-3, -4, -5, -6, -7
D)-3, -5, -7, -9, -11
E)1, 0, -2, -2, -3

To find the first five terms of the sequence $a_n = -n - 2$, substitute $n = 1, 2, 3, 4, 5$ into the formula. For $n = 1$, $a_1 = -(1) - 2 = -3$; for $n = 2$, $a_2 = -(2) - 2 = -4$; for $n = 3$, $a_3 = -(3) - 2 = -5$; for $n = 4$, $a_4 = -(4) - 2 = -6$; for $n = 5$, $a_5 = -(5) - 2 = -7$. Therefore, the first five terms are -3, -4, -5, -6, -7.
