Question : The sum of the first four terms of an AP is 28 and sum of the first eight terms is 88.Find the sum of the first 16 terms of the AP?
Solution:
The average of first 4 terms is 7, while the average of the first 8 terms must be 11
hence d=4/2=2
hence the average of 6th and 7th terms = 15
& the average of 8th and 9th term = 19
But this (19) also represents the average of the 16 term AP
Hence 16*19=304
How average of 6th and 7th terms is 15 ???
How average of 8th and 9th term is 19 ????
Thanks
