Answer 2

Answer :-

• 115 is the 19th term of the A.P : 7 , 13 , 19 , 25.

Step-by-step explanation :-

Given :

• Series : 7 , 13 , 19 , 25
• First term (a) = 7
• Common difference (d) = 6

To find :

• 19th term.

Solution :

nth term of an A.P,

• Sₙ = a + (n - 1)d

Substituting,

⇒ S₁₉ = 7 + (19 - 1)6

⇒ S₁₉ = 7 + (18) × 6

⇒ S₁₉ = 7 + 108

⇒ S₁₉ = 115

• 115 is the 19th term of the A.P : 7 , 13 , 19 , 25.
