Question

Determine the AP whose fifth term is 19 and the difference of the eighth term from the thirteenth term is 200

Answer

a5 = 19

a + 4d = 19 ............. (i)

Also, a13 - a8 = 20

a + 12d - a - 7d = 20

5d = 20 => d = 4 ............ (ii)

From (i) and (ii), you will get the results of 'a' and then can form the AP.....
