Similarly subtract a fixed number from each and every term of A.P. Wri

1.	Similarly subtract a fixed number from each and every term of A.P. Write the resulting numbers as a list.
Answer» 4, 7, 10, 13, 16, …… Subtracting ‘2’ from the each term of A.P in given series, we get 4 – 2, 7 – 2, 10- 2, 13 – 2, 16 – 2, …… 2, 5, 8, 11, 14, …… In the list obtained, the first term a₁ = 2 , a₂ = 5, a₃ = 8, a₄ = 11, Also a₂ – a₁ = 5 – 2 = 3 a₃ – a₂ = 8 – 5 = 3 a₄ – a₃ = 11 – 8 = 3 …………………………………… i.e., d = a₂ – a₁ = a₃ – a₂ = a₄ – a₃ = 3 ∴ The resulting list forms an A.P.

Answer»

4, 7, 10, 13, 16, ……

Subtracting ‘2’ from the each term of A.P in given series, we get

4 – 2, 7 – 2, 10- 2, 13 – 2, 16 – 2, ……

2, 5, 8, 11, 14, ……

In the list obtained, the first term

a₁ = 2 , a₂ = 5, a₃ = 8, a₄ = 11,

Also a₂ – a₁ = 5 – 2 = 3

a₃ – a₂ = 8 – 5 = 3

a₄ – a₃ = 11 – 8 = 3 ……………………………………

i.e., d = a₂ – a₁ = a₃ – a₂ = a₄ – a₃ = 3

∴ The resulting list forms an A.P.
