Answer 1

Answer:

Step-by-step explanation:

A4 + A8 = 24

A6 + A10 = 44

FROM THIS WE GET

A+3D + A + 7D = 24

2A + 10 D = 24

2( A + 5D ) = 24

A+ 5D = 12

A = 12- 5D MARK FOR LATER

NOW ,

A+ 5D + A+ 9D = 44

2A + 14D = 44

2( 12- 5D) + 14D = 44

24- 10D +14D = 44

24 + 4D = 44

4( 6 + D ) = 44

D= 5

NOW ,

A= 12 - 5D

A= 12- 25

A= -13

NOW FOR AP ,

-13, -8, -3 ....AN
