Explanation

The series is 11, ?, 93, 164, 255, 366. Differences: 366-255=111, 255-164=91, 164-93=71. The differences are decreasing by 20. Next difference should be 71-20=51. 93-51=42. Next difference 51-20=31. 42-31=11. The series is 11, 42, 93, 164, 255, 366.

AI explanation

Calculating the differences between the given consecutive terms yields 51, 71, 91, and 111. To find the missing second term, subtract the first difference of 51 from the third term, 93. This gives 93 - 51 = 42. The missing number is 42.
