Solution:
Given sequence 2, 9, 20, 37, 64, 107,
The difference between them is given as 7, 11, 17, 27, 43
17 = 7 + 11 - 1
27 = 17 + 11 - 1
43 = 27 + 17 - 1
Thus the next difference is 43 + 27 - 1 = 69
The missing number in the series is 107+ 69= 176
Summary:
The missing number: 2, 9, 20, 37, 64, 107, in the sequence is 176
