Brother ye automatically chatgpt pe type kysy hojata ha??? Please bana 🙏

Sir cs201 or cs 201p same hi subjects hain

question# 2 correct option is >>> c >>> 3n(n+1)/2

Sir plz is ko pdf file men convert kr den

🥰

meri jan pehly hi question ja answer ap ne ghalat dia ha (x>3) is ka matlab ha "x is greater then 3" not equal to or greater tha 3 because the symbol is greater than or equal is ≥

thanks sir
