Answer:

$\huge\star\underbrace{\mathtt\red{⫷❥ᴀ᭄} \mathtt\green{n~ }\mathtt\blue{ §} \mathtt\purple{₩}\mathtt\orange{Σ} \mathtt\pink{R⫸}}\star\:$

Step-by-step explanation:

☆Given=>A.P=12,7,2,-3.......-98

=>a=12

=>d=-5

☞So let the nth term be -98

=>an=-98

=>a+(n-1)d=an

=>12+(n-1)-5=-98

=>(n-1)-5=-98-12

=>(n-1)-5=-110

=>(n-1)=-110/-5

=>(n-1)=22.

=>n=22+1

So n=23.

☞So the value of n is 23,hence the 23rd term of the given A.P is -98.
