Question

b
In the sequence 9,12,15,18,21.41
u Identify the tenth term​

Answer 1

Step-by-step explanation:

In the given arithmetic series, first term a is 9, common difference d is 3, ( can be obtained by subtracting two consecutive terms ).

We have formula for nth term of AP :-

=> An = a + ( n - 1 ) d

>> Substitute value of n = 10 for 10th term

=> A10 = 9 + ( 10 - 1 ) 3

=> A10 = 9 + ( 9 ) 3

=> A10 = 9 + 27

=> A10 = 36

So the 10th term of AP is 36.
