Question

Is 165 term of the ap 3,6,9,12

Answer 1

Answer:

1. a = 3 ,d = 3 , an = a + (n-1)d n = 165

then find

Answer 2

Answer:

Yes at 55the term

Step-by-step explanation:

See the Given AP the sequence of AP are of multiple of 3

Let first term of AP=a

Let last term of AP=l

let the common difference of AP=d

let no. of term=n

According to question:

we have to tell that 165 is in the AP?

First term of AP=3

Firstly we have to find common difference=d=A2-A1

=6-3=3

Let 165 term of AP be A165

we have,

A165=A+(n-1)d

165=3+(n-1)3

165-3=(n-1)3

162/3=n-1

n=55

The answer is 55th term
