Answer:
Given :
- T1 = a-d / T2 = a / T3 = a+d
- (T1)²+(T2)²+(T3)² = 293
Find = a
- a-d+a+a+d = 27
- 3a = 27
- a = 27/3
- a = 9
Find = d
- (a-d)²+(a)²+(a+d)² = = 293 3a²+2d² 293
- 3(9)²+2d² = 293
- 2d² 293-243
- d² = 50/2
- d = +_5
Find term :
- a-d 9-5 = 4
- a = 9
- a+d = 9+5 = 14
Term is 4, 9, 14
