Find nth term of AP 1,3,5,7------and 2,4,6,8-----.is any term of both AP willsame clarify with reason.​

Answer»

ANSWER:

AP 1,3,5,7

a= 1 , d= 3-1=2

n=?

an= a+ ( n-1) d

= 1+( n-1) ×2

= 1+ 2n-2

= 2n -1---1

AP

2,4,6,8,...

a= 2

d= 4-2= 2

an =?

An = a+(n-1)d

= 2+(n-1) ×2

= 2+2n-2

= 2n--------2)

if nth term is EQUAL then

From EQUATION 1AND 2

2n-1 = 2n

n-1= 2n/2

n-1= n

n= n-1
