Answer: 116
Explanation Now, let's examine the differences between consecutive terms: 17 − 6 = 11 39 − 17 = 22 72 − 39 = 33 The pattern of differences: +11, +22, +33 → increasing by 11 each time. Next difference should be: +44 So, 72 + 44 = 116 Explanation: Differences follow a pattern: +11, +22, +33, +44.
