Answer» Step-by-step explanation: nth TERM of an A.P (an) = PN + q To FIND: Common DIFFERENCE (d) Proof: We know that, an = a + (N – 1)d ⇒ pn + q = a + (n – 1)d [given] ⇒ pn + q – a = (n – 1)d

Answer»

Step-by-step explanation:

nth TERM of an A.P (an) = PN + q

To FIND: Common DIFFERENCE (d)

Proof: We know that,

an = a + (N – 1)d

⇒ pn + q = a + (n – 1)d [given]

⇒ pn + q – a = (n – 1)d
