Sn=4240.....equatn 1 T7=20....equatn 2.. In arithmetic sequnce T7=a+6d therefore ur equation 2 will now be 20=a+6d.....equation 2.make 'a' the subject of the formula and then use TN=a+(n-1)d to solve for d...substitude 20-6d as ur a and ur n is 53 then so...

I meant Sn=4240 meaning S53=4240 coz the n is 53
