Answer:

Four terms are: a-3d,a-d,a+d,a+3d

First three terms is 42

a-3d+a-d+a+d=42

3a-3d=42

a-d=14...........(A)

LAST three terms is 54

a-d+a+d+a+3d=54

3a+3d=54

a+d=18.......... (B)

from (A)&(B)

2a=32

a=16

put the value of a in equation A

a-d=14

16-14=d

2=d

a=16,d=2

i hope it is helpful for you.
