k இன் மதிப்பு; 2, 3 + k மற்றும் 6 ஆனது எண்கணித கூட்டுத் தொடராக இருக்கும்
கருத்து:
கூட்டுத் தொடரின் படி, a2 - a1 = a3 - a2
இங்கே a1 ,a2 ,a3 என்பது ஏதாவதொரு கூட்டுத் தொடரின் 1வது, 2வது மற்றும் 3வது உறுப்பாக ஆக இருக்கும்
கணக்கீடு:
a1 = 2, a2 = k + 3, a3 = 6 என்பது கூட்டுத் தொடரின் மூன்று தொடர்ச்சியான சொற்கூறாக இருக்கும்
கூட்டுத் தொடரின் படி, a2 - a1 = a3 - a2
(k + 3) – 2 = 6 – (k + 3)
⇒ k + 3 - 8 + k + 3 = 0
⇒ 2k = 2
இதைத் தீர்த்த பிறகு, நாம் பெறுவது k = 1
