Answer: -19, -4, 11, 26, 41
Step-by-step explanation:
Sum of 5 consecutive terms = 5 x middle term
∴ middle term = 11
the terms are 11-2d, 11-d, 11, 11+d, 11+2d
Difference between first and last term is 60
(11+2d)-(11-2d)=60
4d = 60
d = 15
Then terms are -19, -4, 11, 26, 41

Let the numbers be a-2d, a-d,a,a+d,a+2d. Now. According to the question...................................a-2d+ a-d+a+ a+d+a+2d=55
5a=55
a=11
Next ,a-2d-(a+2d)=60
a-2d-a-2d=60
-4d =60
d=-15
a-2d= 11-2(-15)=41
a-d=11-(-15)=26
a =11
a+d= 11+(-15)=-4
a+2d =11+2(-15)=-19.
App is 41,26,11,-4,-19 ..
