Answer:

80

Step-by-step explanation:

3rd term

= T(2+1)

= 4T(2)

= 4[ T(1+1)]

= 4[ 4T(1)]

= 4[ 4(5)]

= 4×4×5

= 80

therefore third term = 80

hope this helps you

\sf\red{\underline{\underline{Answer:}}}

\sf{The \ third \ term \ is \ 85.}

\sf\orange{\underline{\underline{Given:}}}

\sf{\implies{t(n+1)=4t(n)+1}}

\sf{\implies{t1=5}}

\sf\pink{\underline{\underline{To \ pink:}}}

\sf{Third \ term.}

\sf\green{\underline{\underline{Solution:}}}

\sf{t(n+1)=4t(n)+1}

\sf{Let \ n \ be \ 1}

\sf{\therefore{t(1+1)=4t1+1}}

\sf{But \ t1=5}

\sf{\therefore{t2=4(5)+1}}

\sf{\therefore{t2=21}}

\sf{Now, \ let \ n \ be \ 2}

\sf{t(2+1)=4t2+1}

\sf{But \ t2=21}

\sf{\therefore{t3=4(21)+1}}

\sf{t3=85}

\sf\purple{\tt{\therefore{The \ third \ term \ is \ 85.}}}
