The pattern of the given number series is as following:
Subtract prime number from each term starting from 23 and in decreasing order.
→ 142,
→ 142 – 23 = 119,
→ 119 – 19 = 100,
→ 100 – 17 = 83,
→ 83 – 13 = 70
→ 70 – 11 = 59,
→ 59 – 7 = 52
Hence, the required wrong term in the given number series is 65. It should be 70.
