Question
The first term a and common difference d are given. Find first four terms of A.P :
$a=200, d=7$
✓
Answer
Given $a=200, d=7$
$
\begin{array}{c}
a=t_1=200 \\
t_2=t_1+d=200+7=207 \\
t_3=t_2+d=207+7=214 \\
t_4=t_3+d=214+7=221 \\
\therefore \text { A.P. is }=200,207,214,221, \ldots
\end{array}
$
$
\begin{array}{c}
a=t_1=200 \\

t_3=t_2+d=207+7=214 \\
t_4=t_3+d=214+7=221 \\
\therefore \text { A.P. is }=200,207,214,221, \ldots
