If a=20 and d=3 then find tn
Answers
Answer:
Here is answer :-
- Using formula of A. P
- Given :- a = 20 , d = 3
- Find :- tn
solution :-
- Now,
- tn = a + (n -1 ) x d
- tn = 20 + ( n - 1) x 3
- tn = 20 n x 3
- tn = 60 / n
- tn = 60
Answer :-
- tn = 60
Hope it help to u plz mark as brainliest and thank my this answer and.
If a = 20 and d = 3 then tₙ = 3n + 17
Given :
a = 20 and d = 3
To find :
The value of tₙ
Formula :
If in an arithmetic progression
First term = a
Common difference = d
Then nth term of the AP
= a + ( n - 1 )d
Solution :
Step 1 of 2 :
Write down the first term and common difference
Here it is given that ,
First term = a = 20
Common Difference = d = 3
Step 2 of 2 :
Find the value of tₙ
The value of tₙ
= nth term of the AP
= a + ( n - 1 )d
= 20 + ( n - 1 ) × 3
= 20 + 3n - 3
= 3n + 17
