K విలువ కోసం; 2, 3 + k మరియు 6 AP లో ఉండాలి
భావన:
అంకగణిత పురోగతి ప్రకారం, a2 - a1 = a3 - a2
ఇక్కడ a1 ,a2 ,a3 అనేది ఏదైనా AP యొక్క 1వ, 2వ మరియు 3వ పదాలు
లెక్కింపు:
a 1 = 2, a 2 = k + 3, a 3 = 6 అనేది AP యొక్క వరుసగా మూడు పదాలు
అంకగణిత పురోగతి ప్రకారం, a 2 - a 1 = a 3 - a 2
(k + 3) – 2 = 6 – (k + 3)
⇒ k + 3 - 8 + k + 3 = 0
⇒ 2k = 2
పరిష్కరించిన తరువాత, మనకు k = 1 లభిస్తుంది
