The pattern of the given series is:
⇒ 13 + 13 - 1 = 13 + 1 - 1 = 13
⇒ 13 + 23 - 2 = 13 + 8 - 2 = 19
⇒ 19 + 33 - 3 = 19 + 27 - 3 = 43
⇒ 43 + 43 - 4 = 43 + 64 - 4 = 103
⇒ 103 + 53 - 5 = 103 + 125 - 5 = 223 = ?
⇒ 13 + 13 - 1 = 13 + 1 - 1 = 13
⇒ 13 + 23 - 2 = 13 + 8 - 2 = 19
⇒ 19 + 33 - 3 = 19 + 27 - 3 = 43
⇒ 43 + 43 - 4 = 43 + 64 - 4 = 103
⇒ 103 + 53 - 5 = 103 + 125 - 5 = 223 = ?
