Answer 1

a) a = 6

d = 2

a5 = a + 4d = 6 + 8 = 14

b) a = 1

d = 1/3

a5 = a + 4d = 1 + 4/3 = 7/3

Hope it helps!!

Thank you ✌️

Answer 2

a) a=6 , d=-2

=>$a_{5}=a+(5-1)×d$

=>$a_{5}=6+[4×(-2)]$

=>$a_{5}=-2$

b)a=1 , $d=\frac{-1}{3}$

=>$a_5=a+(5-1)×d$

=>$a_{5}=1+[4×(\frac{-1}{3})]$

=>$a_5=1-\frac{4}{3}$

=>$a_5=\frac{-1}{3}$
