In this Blog, we Describe the Important Formulas of an AP & GP.
1) tn = a + (n - 1) d
2) Sn = n * (a + l)/2
3) Sn = n * [ 2 a + (n - 1) d ) ] / 2
Now we will see some examples:
Problems related to tn = a + (n - 1) d:
A) Find nth term of an AP 3, 5, 7, 9 ...
Solution:
1) Here a = 3, d = (5 - 3) = 2 so, d = 2.
2) We know that
Now we will see some examples:
Problems related to tn = a + (n - 1) d:
A) Find nth term of an AP 3, 5, 7, 9 ...
Solution:
1) Here a = 3, d = (5 - 3) = 2 so, d = 2.
2) We know that
tn = a + (n -1) d
= 3 + (n -1) (2)
= 3 + (2 n - 2)
= 1 + (2 n)
= (2 n) + 1
3) Answer: Here the nth term of an AP is tn = (2 n) + 1
= 3 + (n -1) (2)
= 3 + (2 n - 2)
= 1 + (2 n)
= (2 n) + 1
3) Answer: Here the nth term of an AP is tn = (2 n) + 1
