​

Answer 1

Step-by-step explanation:

a5 a+ 4d

-3+4(-3)

-3-12

-15

Answer 2

Given :-

• a = -3

• d = -3

• n = 5

To Find :-

• Fifth term($\sf\ a_{5}$)

Answer :-

• -15

Concept Used :-

• $\sf\ a_{n}=a+(n-1)d$

Solution :-

$\longrightarrow\sf\ a_{n}=a+(n-1)d$

$\longrightarrow\sf\ a_{5}=-3+(5-1)(-3)$

$\longrightarrow\sf\ a_{5}=-3+4(-3)$

$\longrightarrow\sf\ a_{5}=-3-12$

$\sf{\boxed{\boxed{\red{\dag{\ a_{5}=-15}}}}}$

$\bf{ \underline{So\:,\:fifth\:term\:of\:this\:\ a_{p}\: is \:-15}}$
