Answer:therefore the three terms are,

a-d = 8-4=4

a=8

a+d=8+4=12

Step-by-step explanation:

let the terms be a-d, a, a+d

sum=24

a-d+a+a+d=3a=24

a=8

(a-d) ^2+a^2+(a+d)^2=224

a^2+2(a^2+d^2)=224

3a^2+2d^2=224

3(64)+2d^2=224

2d^2=224-192

d^2=32/2

d=√16=4 put in numbers(assumed)

therefore the three terms are,

a-d = 8-4=4

a=8

a+d=8+4=12
