Given: a1 = a = 5 ….. (1) 

a4 = a + 3d = 9\(\frac{1}{2}\) ….. (2) 

Solving equations (1) and (2);

⇒ 3d = 4\(\frac{1}{2}\) 

⇒ 3d = \(\frac{9}{2}\)

⇒ d = \(\frac{9}{2\times3}\) = \(\frac{3}{2}\)

∴ a2 = a + d = 5 + \(\frac{3}{2}\)\(\frac{13}{2}\)

a3 = a + 2d = 5 + 2 × \(\frac{3}{2}\) = 5 + 3 = 8
