Step-by-step explanation:

$a_1 = - 1.50 \\ \\ a_2 = a_1 + d \\ a_2 = - 1.50 + ( - 0.50) \\ a_ 2= - 1.50 - 0.50 \\ a_2 = - 2 \\ \\ a_3 = a_2 + d \\ a_3 = - 2 + ( - 0.50) \\ a_3 = - 2 - 0.50 \\ a_ 3= - 2 . 5 \\ \\ a_4 = a_3 + d \\ a_4 = - 2.5 + ( - 0.50) \\ a_ 4= - 2.5 - 0.50 \\ a_4 = - 3$

∴ First 4 terms are -1.50, -2, -2.5, -3
