Find the wrong term in the following number series- 20 39 67 102 158 225

The series is 20, 39, 67, 102, 158, 225. Analyzing the pattern: Differences are +19, +28, +35, +56, +67. The second-level differences show +9, +7, +21, +11. If we consider that 102 should have been 103, then: 20, 39, 67, 103, 158, 225 with differences +19, +28, +36, +55, +67. This creates a cleaner alternating pattern or follows a modified progression. The number 102 is indeed the wrong term that breaks the underlying pattern.
