Answer:
The five terms in AP are 12 ,18 ,24 ,30 and 36 .
Step-by-step explanation:
Let the 5 terms are (a-2d) ,(a-d) ,a ,(a+d) and (a+2d) .
a-2d + a-d + a + a+d + a+2d = 120
5a = 120
a = 24
a+2d = 6 + a-2d + a-d
2d = 6 + a-3d
5d = 6 + a
5d = 6 + 24
5d = 30
d = 6
a - 2d = 24 - 2(6) = 24 - 12 = 12
a - d = 24 - 6 = 18
a = 24
a + d = 24 + 6 = 30
a + 2d = 24 + 2(6) = 24 + 12 = 36
Therefore ,the 5 terms are 12 ,18 ,24 ,30 and 36 .
