Question

if the 3rd and 9th term of an A.P are -4 and -8 respect.​

Answer 1

Answer:

HERE IS UR ANSWER DEAR!!!

3rd term = a+2d = -4

9th term = a+8d = -8

by elimination method,

-6d= 4

d= -4/6

d= -2/3

sub/: d= -2/3 in 3rd term equation :

3rd term = a+ 2d = -4

a+ 2 ( -2/3 ) = -4

a+ -4/3. = -4

a. = -4 + 4/3

a = ( -12 +4)/3

a = -8/3

therefore...

a= -8/3

d= -2/3
