Question

Question 1 (v)
Fill in the blanks in the following table, given that a is the first term, d the common difference and $a_n$ the $n^{th}$ term of the A.P.
$\begin{array}{ccccc}& a& d& n& a_n\\ \left(v\right)& 3.5& 0& 105& \dots \dots \end{array}$

Answer 1

(v) $a=3.5,d=0,n=105,a_n=$?
We know that,
$a_n=a+(n-1)d{a}_n=3.5+(105-1)0a_n=3.5+104\times 0a_n=3.5$
