Question

Find with term of an ap whose and term is 3n-
5

Answer 1

A.P = -2,1,4... First term (a)=-2 common difference =3

Given nth term of A.P 3n-5

First term of A.P = $a_{1}$ = 3(1)-5 = 3-5 = -2 (put n=1)

for the second term put n=2 $a_{2}$= 3(2)-5 =6-5 = 1

for the third term put n = 3 $a_{3}$ = 3(3)-5= 9-5= 4

A.P with nth term 3n-5 is -2,1,4 .....
