Find the missing term in the series.
72, 85, 105, ?, 162, 197The series follows the following pattern:
⇒ 72 + 13 = 85
⇒ 85 + 20 = 105 (13 + 7 = 20)
⇒ 105 + 26 = 131 (20 + 6 = 26) = ?
⇒ 131 + 31 = 162 (26 + 5 = 31)
⇒ 162 + 35 = 197 (31 + 4 = 35)
∴ ? = 1311. Find the wrong term in the following number series. 1788, 892, 444, 220, 112, 52, 24
