Write the first four terms of the A.P. when its first term is

$-5$

and the common difference is

$-3$

.

From the question it is given that,

First term a =

$-5$

Common difference d =

$-3$

Then the first four terms are =

$\text{ }5\text{ }+\text{ }\left( -3 \right)\text{ }=\text{ }-5\text{ }\text{ }3\text{ }=\text{ }\text{ }8$

$\begin{array}{*{35}{l}} -8\text{ }+\text{ }\left( -3 \right)\text{ }=\text{ }\text{ }8\text{ }\text{ }3\text{ }=\text{ }-11 \\ \text{ }11\text{ }+\text{ }\left( -3 \right)\text{ }=\text{ }\text{ }11\text{ }\text{ }3\text{ }=\text{ }\text{ }14 \\ \end{array}$

Therefore, first four terms are

$-5,\text{ }-8,\text{ }-11\text{ }and\text{ }-14$
