Show answer & explanation
Correct answer: A
Look at the differences between consecutive terms:
344 → 278 = −66
278 → 223 = −55
223 → 179 = −44
179 → 146 = −33
The differences decrease by 11 each time, so the next difference is −22.
Compute the next term: 146 − 22 = 124
Check the following term: 124 − 11 = 113
Final answer: 124
