The first term of an AP is 6 and the common difference 3 respectively . Find the third term

Answer 1

QUE. The first term of an AP is 6 and the common difference 3 respectively . Find the third term.

$\boxed{\boxed{\huge{\bf{Answer}}}}$

According to the question,

first term of an A.P. is 6

a = 6

common difference of the A.P. 3

d = 3

We have to find the 3rd term

n = 3

Nth term of an A.P. = a + (n-1)d

= 6 + (3 - 1)3

= 6 + 2 × 3

= 6 + 6

= 12

Hence third term of the A.P. is 12.

Answer 2

$\huge{\mathfrak{\underline{\underline{Question :}}}}$

The first term of an AP is 6 and the common difference 3 respectively . Find the third term.

$\huge{\bf{Solution}}$

According to the question,

first term of an A.P. is 6

a = 6

common difference of the A.P. is 3

d = 3

We have to find the 3rd term

n = 3

Nth term of an A.P. = a + (n-1)d

= 6 + (3 - 1)3

= 6 + 2 × 3

= 6 + 6

= 12

Hence third term of the A.P. is 12.
