One can find the number of terms by using the nth term formula and the sum formula.
a(n)= a+(n-1)d where n is the number of term in which nth term occur.
S(n)=n/2[2a+(n-1)d]
=n/2[a+l](l=last term)
where n is the number of terms of sum of terms.
Hope it us clear to you mark as the brainliest please

To find number of terms there are many methods...... 1.) If the sinple series is given then you can find it by using the formula...
Nth term = a+ (n-1)d
2.) If the sum of series is given then u can find it by..... Formula....
Sum= n/2+(2a+(n-1)d....
I hope it helps.....
Nth term = a+ (n-1)d
2.) If the sum of series is given then u can find it by..... Formula....
Sum= n/2+(2a+(n-1)d....
I hope it helps.....
