Answer 2

Required Answer :

The first four terms of A.P. are 1,2,3 and 4

Given :

• First term = 1
• Common difference = 1

To find :

• First four terms of arithmetic progression

Knowledge required :

Formula to the find the n terms :

• tₙ = a + (n - 1)d

where,

• a denotes the first term
• n denotes the number of terms
• d denotes the common difference

Solution :

First term :

⇒ t₁ = a + (n - 1)d

⇒ t₁ = 1 + (1 - 1)(1)

⇒ t₁ = 1 + (0)(1)

⇒ t₁ = 0

First term = 0

Second term :

⇒ t₂ = a + (n - 1)d

⇒ t₂ = 1 + (2 - 1)(1)

⇒ t₂ = 1 + (1)(1)

⇒ t₂ = 1 + 1

⇒ t₂ = 2

Second term = 2

Third term :

⇒ t₃ = a + (n - 1)d

⇒ t₃ = 1 + (3 - 1)(1)

⇒ t₃ = 1 + (2)(1)

⇒ t₃ = 1 + 2

⇒ t₃ = 3

Third term = 3

Fourth term :

⇒ t₄ = a + (n - 1)d

⇒ t₄ = 1 + (4 - 1)(1)

⇒ t₄ = 1 + (3)(1)

⇒ t₄ = 1 + 3

⇒ t₄ = 4

Fourth term = 4

Therefore, the first four terms of A.P. are 1,2,3 and 4
