In the following number series find the wrong term. 8 59 358 1796 7186 21565

Find the pattern: 8 × 7 + 3 = 59, 59 × 6 + 4 = 358, 358 × 5 + 6 = 1796, 1796 × 4 + 6 = 7190 (not 7186). The pattern is multiply by decreasing numbers (7, 6, 5, 4...) and add numbers that increase (3, 4, 6, 6...). However, 1796 × 4 + 6 = 7190, not 7186. The term 1796 is correct in the pattern, but 7186 should be 7190. Wait - let me recheck. Actually 7186 appears in the series, so 1796 must be the wrong term because the pattern breaks there.
