The pattern is as follows:
⇒ (13 × 1/2) + 6.5 = 13
⇒ (13 × 1) + 7 = 20
⇒ (20 × 3/2) + 7.5 = 37.5
⇒ (37.5 × 2) + 8 = 83
⇒ (83 × 5/2) + 8.5 = 216 ≠ 214
∴ 214 is wrong and should be replaced by 216.
⇒ (13 × 1/2) + 6.5 = 13
⇒ (13 × 1) + 7 = 20
⇒ (20 × 3/2) + 7.5 = 37.5
⇒ (37.5 × 2) + 8 = 83
⇒ (83 × 5/2) + 8.5 = 216 ≠ 214
∴ 214 is wrong and should be replaced by 216.
