Question
Write the arithmetic progression when first term a and common difference d are as following:
a = -1.5, d = -0.5.
a = -1.5, d = -0.5.
✓
Answer
First term (a) = -1.5
and common difference (d) = -0.5
$\therefore$ Second term = a + d = -1.5 + (-0.5)
= -1.5 - 0.5 = -2.0
Third term = a + 2d = -1.5 + 2(-0.5)
= -1.5 - 1.0 = -2.5
Fourth term = a + 3d = -1.5 + 3(0.5)
= -1.5 - 1.5 = -3.0
Fifth term = a + 4d = -1.5 + 4(-0.5)
= -1.5 - 2.0 = -3.5
$\therefore$ AP Will be -1.5, -2.0, -2.5, -3.0, -3.5, .....
