• Find the 25th term of the AP 10,7,4,.....

$\huge\pink{\boxed{\green {\mathbb{\overbrace {\underbrace{\fcolorbox{red}{aqua}{\underline{\pink{Answer}}}}}}}}}$

Here's given our A.P: 10,7,4...

Clearly from our A.P, we get:

• First Term (a) →10
• Common Difference (d)→(7-10)→ -3
• nth term (n)→25

Now:

As we know, nth term of an A.P is given by:

a+(n-1)d

Therefore:

25th term of this A.P, by putting the all the values:

=10+{(25-1)-3}

=10+24×(-3)

=10+(-72)

=10-72

=-62

Hence 25th term of this A.P is -62
