In an arithmatic sequence, sum of 9 terms is 279 and sum of 20 terms is 1280. Find 5th term ? Find 16th term ? Write the sequence.

Join the centers of the 3 triangles to form an equilateral triangle with sides length 20. The area enclosed by the 3 triangles will be the area of this triangle minus the area of 3 sectors of the circles with central angles of 60 degrees. Thus the area of...

S9 = 279 F5 = 279/9 = 31 S20 = 1280 S20-S9 = 1280-279 =1001 =[sum of F11 to F20] F15 =1001/11 = 91. F15-F5 = 91-31 = 60 = 10 d d = 60/10 = 6 F16 = 91 + 6 =97 F1 =31-4d =31-24= 7 so, 7,13,19,25,..........
