Question

If a = – 1.25, d = – 0.25 then 6th term is​

Answer 1

Answer:

-2.5

Step-by-step explanation:

If the numbers are in Arithmetic Progression, and

First term, a = -1.25;

common difference, d = -0.25

nth term = a + (n-1)*d

6th term = a + (6-1)*d

6th term = a + 5d

6th term = -1.25 + 5(-0.25)

6th term = -1.25 -1.25

6th term = -2.5

Answer 2

Given :

first term of an A.P. (a) = -1.25

common difference (d) = -0.25

To find the 6th term of A.P.

Applying formula a+(n-1)d ,

T6 = a+(n-1)d

= -1.25+(6-1)-0.25

= -1.25 + 5× -0.25

= -1.25 + (-1.25)

= -1.25 - 1.25

= -2.50

The 6th term of A.P. is -2.50
