Answer» Let three term in an AP. 4m+8,2m^2+3m+6,3m^2+4m+4 As you know that if term are in a AP then it s common difference are equal so. d=t2-t1=2m^2+3m+6-4m-8 d=2m^2-m-2---------1) and again......similarly d=t3-t2. d=3m^2+4m+4-2m^2-3m-6 d=m^2+m-2 ------2) from 1) and 2) we get, m^2+m-2=2m^2-m-2 =)m^2-2m=0 =)m(m-2)=0 m=0 ---1) and m=2,HIT THE LIKE BUTTON

20)1f4m + 8,2m2 + 3m + 6,3m2 + 4m+4 are three consecutive terms of an A.P. findM.

Answer»

Let three term in an AP.

4m+8,2m^2+3m+6,3m^2+4m+4

As you know that if term are in a AP then it s common difference are equal so.

d=t2-t1=2m^2+3m+6-4m-8

d=2m^2-m-2---------1)

and again......similarly

d=t3-t2.

d=3m^2+4m+4-2m^2-3m-6

d=m^2+m-2 ------2)

from 1) and 2)

we get,

m^2+m-2=2m^2-m-2

=)m^2-2m=0

=)m(m-2)=0

m=0 ---1)

and m=2,HIT THE LIKE BUTTON
