After Being Set Up, A Company Manufactured 6000 Scooters In The Third

1.	After Being Set Up, A Company Manufactured 6000 Scooters In The Third Year And 7000 Scooters In The Seventh Year. Assuming That The Production Increases Uniformly By A Fixed Number Every Year, What Is The Production In The Tenth Year?
Answer» You can USE A.P.,Tn =a+(n-1)d ,6000=a+2d.....(1) and 7000 = a + 6d .....(2) EQN (2) – Eqn (1) ⇒ 1000=4d, i.e. d = 250 and a = 6000 − 500 = 5500 T10 =5500 + 9 × 250 =7750 You can use A.P.,Tn =a+(n-1)d ,6000=a+2d.....(1) and 7000 = a + 6d .....(2) Eqn (2) – Eqn (1) ⇒ 1000=4d, i.e. d = 250 and a = 6000 − 500 = 5500 T10 =5500 + 9 × 250 =7750

You can USE A.P.,Tn =a+(n-1)d ,6000=a+2d.....(1) and 7000 = a + 6d .....(2)

EQN (2) – Eqn (1) ⇒ 1000=4d,

i.e. d = 250 and a = 6000 − 500 = 5500

T10 =5500 + 9 × 250 =7750

You can use A.P.,Tn =a+(n-1)d ,6000=a+2d.....(1) and 7000 = a + 6d .....(2)

Eqn (2) – Eqn (1) ⇒ 1000=4d,

i.e. d = 250 and a = 6000 − 500 = 5500

T10 =5500 + 9 × 250 =7750
