Answer :
Explanation :
Given :–
- a₁₀ = 52
- a₁₇ = a₁₃ + 20
To Find :–
- Sequence of the A.P. (Arithmetic Progression)
Formula Applied :–
Solution :–
We have ,
We also know that :
Putting this value of 'd' in Equation(1) :-
Now we will find terms of the A.P. :-
☆ First Term :-
⇒ a₁ = 7
☆ Second Term :-
⇒ a₂ = a + (2 - 1)d
⇒ a₂ = 7 + 5
⇒ a₂ = 12
☆ Third Term :-
⇒ a₃ = a + (3 - 1)d
⇒ a₃ = 7 + 2(5)
⇒ a₃ = 7 + 10
⇒ a₃ = 17
∴ The sequence of the A.P. will be 7 , 12 , 17 ,...
