Answer:
Step-by-step explanation:
<u>This is a sum of the first n terms of an AP:</u>
<u>The true sum is between 92 and 145:</u>
- 92 < n(n + 1)/2 < 145
- 184 < n(n + 1) < 290
- 184 < n² + n < 290
- 185 < (n + 1/2)² < 291
- √185 < n + 1/2 < √291
- 14 ≤ n < 17
<u>Let n = 14</u>
<u>Let n = 15</u>
<u>Let n = 16</u>
