Question 9 of ncert of ex 9.2 series and sequences |
| Answer» Listen do example no.6 and you are thinking in the example that why n=23 because it is not given . Since for 12th term a+11d means that n is there 12 = a +(12 - 1)d = a+11d. So comparing eq. 1 of example 6 then it is 2a +n-1 .d so 11th term is a +11 so by comparing we put in 11th term as 2 and then we do 2.12 - 1 we get 23. | |
