Step-by-step explanation:
Third year produced = 250
a3=250
a+2d = 250 - (1)
Seventh year produced = 450
a7 = 450
a+6d = 450
Subtract equation 1 and 2
a+2d=250
a+6d=450
4d=200
d=50
d=50, In equation 1
a+2x50=250
a=250-100
a=150
i) Frist year = 150
ii) Production in 10 year
a10 = a+9d
a10 = 150+9(50)
a10 = 150+450
a10 = 600
iii) Total production of first 15 years
s15 =7500
