Write the arithmetic progression when first term a and common differen

1.	Write the arithmetic progression when first term a and common difference d are:a = –1.5, d = – 0.5
Answer» Given First term (a) = –1.5 Common difference (d) = – 0 5 Then arithmetic progression is; a, a + d, a + 2d, a + 3d, …… ⇒ -1.5, -1.5, -0.5, –1.5 + 2(– 0.5), –1.5 + 3(– 0.5) ⇒ – 1.5, – 2, – 2.5, – 3, …….

Write the arithmetic progression when first term a and common difference d are:a = –1.5, d = – 0.5

Answer»

Given First term (a) = –1.5

Common difference (d) = – 0 5

Then arithmetic progression is; a, a + d, a + 2d, a + 3d, ……

⇒ -1.5, -1.5, -0.5, –1.5 + 2(– 0.5), –1.5 + 3(– 0.5)

⇒ – 1.5, – 2, – 2.5, – 3, …….
