Answer:

\huge{{\boxed{\boxed{\pink{\underline{\green{\mathscr{{\huge{\underline{\bf{\pink{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
