Question

{x:x is a 4th term of AP 10,6,2}

Answer 1

Answer:

4th term is -2

Step-by-step explanation:

a↓4=10+(4-1)-4

=10+(3)-4

=10-12

=-2

Answer 2

The 4th term of an AP, $a_{4}$ = - 2

Step-by-step explanation:

The given AP:

10, 6, 2

Here, first term(a) = 10, common difference(d) = 6 - 10 = - 4 and

the number of term(n) = 4

To find, the fourth term of an AP, $a_{4}$ = ?

We know that,

The nth term of an AP

$a_{n}$ = a + (n - 1) d

∴ The 4th term of an AP,

$a_{4}$ = 10 + (4 - 1)( - 4)

⇒ $a_{4}$ = 10 + (3)( - 4)

⇒ $a_{4}$ = 10 - 12 = - 2

∴ The 4th term of an AP, $a_{4}$ = - 2

Thus, the 4th term of an AP, $a_{4}$ is - 2.
