💡 Analysis & Explanation
Sequence Observation
Look at the direct numerical progression and calculate the step differences between adjacent terms.
First Phase Difference
55 - 37 = 18; followed by 66 - 55 = 11.
Second Phase Difference
84 - 66 = 18; followed by 95 - 84 = 11.
Third Phase Difference
113 - 95 = 18. The pattern dictates an alternating +18, +11 jump.
Final Calculation
The next required jump is +11. So, 113 + 11 = 124.
Conclusion
The series logically concludes with the number 124.
