Question

The third term of an


a.P is -11 and ninth term is -35 then the nth term is

Answer 1

Answer: the “n”th term is 1 - 4n

Step-by-step explanation:

Let the first term be “a” and the common difference be “d”

To find the “n”th term of an AP, we use the formula

=> a + (n-1)*d = “n”th term

Using the above formula for the question

=> a + (3-1)*d = -11 and a + (9-1)*d = -35

=> a + 2d = -11 and a + 8d = -35

Subtraction of the two equation gives us

=> d = -4 and a = -3

The “n” the term of the AP will be

=> a + (n-1)d

=> (-3) + (n-1)(-4)

=> -3 -4n +4

=> 1 - 4n
