5 তম = 52
11 তম = 184
ব্যবহৃত সূত্র:
an = a1 + (n - 1) × d
an = n তম সংখ্যা
a1 = ক্রমের ১ম সংখ্যা
d = সংখ্যার পার্থক্য
গণনা:
প্রশ্নানুযায়ী:
⇒ a1 + (5 - 1) d = 52
⇒ a1 + (17 - 1) d = 184
⇒ a1 + 4d = 52 ---(i)
⇒ a1 + 16d = 184 ---(ii)
উভয়কে সমানভাবে বর্ণনা করার পর আমরা যে সমীকরণটি পাই তা হল
⇒ d = 11
∴ অপরিহার্য সাধারণ পার্থক্য = 11Last updated on Jul 22, 2025
