Question
Write first four terms of the A.P. when the first term a and the common difference $d$ are given as follows : $a =\frac{1}{2}, d =-\frac{1}{6}$
✓

Answer

$\begin{aligned} & a =\frac{1}{2}, d =-\frac{1}{6} \\ & \text { A.P. is } \frac{1}{2},\left(\frac{1}{2}, \frac{1}{6}\right)=\frac{2}{6} \\ & =\frac{2}{6}-\frac{1}{6}=\frac{1}{6}, \ldots \\ & \text { A.P. }=\frac{1}{2}, \frac{2}{6}, \frac{1}{6}, 0, \ldots \\ & =\frac{1}{2}, \frac{1}{3}, \frac{1}{6}, 0, \ldots\end{aligned}$
