krishnasharma142002: Because my answer is different from your answer

ravitejaamanaganti: First term = - 4 and Common difference = 3 and apply sum of n terms formula with n=x you will get the first equation and with you you will get a quadratic quation by factorization method you will get xvalue

ravitejaamanaganti: sum of n terms = n/2 (2a +(n-1)d), n =x, a =-4,d=3

krishnasharma142002: See my method
