Question

Q1. Write an A.P. whose first term is a and common difference d in each of the following.
i) a = -1.25. d = 3
ii) a =6, d=-3
iii) a = -19, d=-4​

Answer 1

i) a = -1.25. d = 3

First term(a) =-1.25

Second term(a2)=a+d=-1.25+3=1.75

Third term(a3)=a+2d=-1.25+2(3)=-1.25+6=4.75

Fourth term(a4)=a+3d=-1.25+3(3)=-1.25+9=7.75

Series:-1.25,1.75,4.75,7.75....

ii) a =6, d=-3

First term(a1)=6

Second term(a2)=a+d=6-3=3

Third term(a3)=a+2d=6+2(-3)=6-6=0

Fourth term(a4)=a+3d=6+3(-3)=6-9=-3

Series:6,3,0,-3

iii) a = -19, d=-4

First term(a1)=a=-19

Second term(a2)=a+d=-19-4=-23

Third term(a3)=a+2d=-19+2(-4)=-19-8=-27

Fourth term(a4)=a+3d=-19+3(-4)=-19-12=-31

Series:-19,-23,-27,-31
