Question

In an arithmetic sequence with a1 = 4 and d = 9, which term is 184?

Answer 1

$\huge\bold{Answer:-}$

Given:-

• The First term of an Ap is 4
• The common difference of an Ap is 9 .

To Find:-

• The number of term which is 184.

Solution:-

let, the nth term of an Ap be 184

so,

➱ an = a + ( n - 1 )d

➱ 184 = 4 + ( n -1 ) 9

➱ 180 = ( n - 1) 9

➱ n - 1 = $\dfrac{180} {9}$

➱ n -1 = 20

➱ n = 21

Therefore , the 21 th term of an Ap is 184 .
