Find the respective terms for the following APs.a1 = 2, a3 = 26, find a2

Given that a1 = 2 & a3 = 26That means a3 = a1 + (3-1)d⇒ 26 = 2 + 2d⇒ 24 = 2d⇒ d = 12∴ a2 = a1 + (2-1)d⇒ a2 = 2 + 12 = 14

Find the respective terms for the following APs.
a₁ = 2, a₃ = 26, find a₂

Given that a₁ = 2 & a₃ = 26

That means a₃ = a₁ + (3-1)d

⇒ 26 = 2 + 2d

⇒ 24 = 2d

⇒ d = 12

∴ a₂ = a₁ + (2-1)d

⇒ a₂ = 2 + 12 = 14
