Answer:

solution given a-d ,a, a+d, a+2d are in A.P

according to the question

sum of 4 terms =12

a-d+a+a+d+a+2d=12

4a+2d=12

2a+d=12/2

d=6-2a

again

3rd + 4rt term =14

a+d+a+2d=14

2a+3d=14

substituting value of d

2a+3(6-2a)=14

2a+18-6a=14

18-14=4a

a=4/4=1

again

d=6-2×1=4

first term =a-d=1-4=-3

second term =a=1

third term =a+d=1+3=4

forth term =a+2d=1+3×2=7
