154 - 147 = 7
147 - 136 = 11
136 - 123 = 13
123 - 106 = 17
The differences between consecutive terms are 7, 11, 13, and 17. These differences are increasing by prime numbers.
The next difference should be 5 (the previous prime number before 7).
Now, add 5 to 154 to find the missing number:
154 + 5 = 159
∴ The missing term in the series is 159.
