Answer» In general, for an AP a1, a2, . . . .,an, we have d = ak+1 - ak where ak+1 and ak are the (k+1)th and kth terms respectively. For the list of numbers: 147, 148, 149, 150, ... a2 – a1 = 148 – 147 = 1 a3 – a2 = 149 – 148 = 1 a4 – a3 = 150 – 149 = 1 Here, the difference of any two consecutive terms in each case is -1. So, the given list is an AP whose first term a is 147 and common difference d is 1. |
