Please divya dii don't go.
And this answer ok .​

Answer 1

Answer: Answer:

The 7th term is the first negative term.

Step-by-step explanation:

In the given question,

We can conclude that the first term

a = 25

And the common difference(d)

d = 20-25

d = - 5

For finding the A. P. :-

We can use the formula

An = a+(n-1)d

As we know:-

For the first negative term it should be less than 0.

So the required equation will be :

=> a+(n-1)d<0

=> 25+(n-1)*(-5)<0

=> (n-1)*(-5)<-25

=>(n-1)>5

=> n>6

Therefore-:

The first negative term is it's 7th term. have a nice dayy
