E Correct answer
Explanation

Calculate differences: 119 - 80 = 39, 166 - 119 = 47, 221 - 166 = 55, 223 - 221 = 2. The differences 39, 47, 55 increase by 8 each time. The next difference should be 55 + 8 = 63, making the last term 221 + 63 = 284, not 223. Option E (223) is correct as the wrong term. Option D (192) is a distractor not in the series.
