who can find plz help​

Answer 1

Answer:

$\huge\rm\color{purple}{\underline{\underline{Part\:1→}}}$

$\bold{\underline{\underline{Given→}}}$

• $\rm\green{A.P=3,5,7,........}$
• $\rm\green{1^{st}Term(a)=3}$
• $\rm\green{Common\:difference(d)=5}$

$\bold{\underline{\underline{To\:Find→}}}$

$\rm\purple{→100^{th}Term\:of\:the\:A.P}$

$\bold{\underline{\underline{Answer→}}}$

$\rm\red{\underline{\underline{For\:n^{th}Term}}}$ = $\rm{an_{th}=a+(n-1)d}$

For $\bold{\underline{100^{th}}}$ Term:-

$\rm{\dashrightarrow{an=a+(n-1)d}}$

$\rm{\dashrightarrow{a100=a+(100-1)d}}$

$\rm{\dashrightarrow{a100=a+(99)d}}$

$\rm\blue{→a100=a+(99)d}$

$\rm\blue{→a100=3+(99)2}$

$\rm\blue{→a100=3+198}$

$\rm\blue{→a100=201}$

${\boxed{\boxed{\pink{\rm{→a100=201✔}}}}}$

$\huge\rm\color{orange}{\underline{\underline{Part\:2→}}}$

$\bold{\underline{\underline{Given→}}}$

• $\rm\green{A.P=2,5,8}$
• $\rm\green{1^{st}Term(a)=2}$
• $\rm\green{Common\:diference(d)=3}$

$\bold{\underline{\underline{To\:Find→}}}$

$\rm\purple{Algebraic\:form\:of\:the\:equation}$

$\bold{\underline{\underline{Answer→}}}$

As the algebraic form for the $\bold{n^{th}}$ term is a+(n-1)d

$\sf\red{\underline{\underline{Algebraic\:Form→}}}$

$\rm\blue{→an=a+(n-1)d}$

$\rm\blue{→an=2+(n-1)3}$

$\rm\blue{→an=2+3(n)+3(-1)}$

$\rm\blue{→an=3n+(2-3)}$

$\rm\blue{→an=3n-1}$

${\boxed{\boxed{\rm{\pink{→an=3n-1}}}}}$

VERIFICATION:-

$\sf\red{\underline{\underline{For\:1^{st}Term→}}}$ Putting n=1.

$\rm\color{blue}{→an=3n-1}$

$\rm\color{blue}{→a1=3(1)-1}$

$\rm\color{blue}{→a1=3-1}$

$\rm\color{blue}{→a1=2}$

${\boxed{\boxed{\rm{\pink{→a1=2✔}}}}}$

$\sf\red{\underline{\underline{For\:2^{nd}Term→}}}$ Putting n=2.

$\rm\color{darkblue}{→an=3n-1}$

$\rm\color{darkblue}{→a2=3(2)-1}$

$\rm\color{darkblue}{→a2=6-1}$

$\rm\color{darkblue}{→a2=5}$

${\boxed{\boxed{\rm{\pink{→a2=5✔}}}}}$

$\sf\red{\underline{\underline{For\:3^{rd}Term→}}}$ Putting n=3.

$\rm\color{steelblue}{→an=3n-1}$

$\rm\color{steelblue}{→a3=3(3)-1}$

$\rm\color{steelblue}{→a3=9-1}$

$\rm\color{steelblue}{→a3=8}$

${\boxed{\boxed{\rm{\pink{→a3=8✔}}}}}$

Hence Verified✅

☞So 3n-1 is the verified algebraic form of the given sequence.

HOPE IT HELPS.
