An AP consists of 21 termsThe sum of the three terms in the middle is 129 and of the last three is 237Find the AP?
The sum of the 10th, 11th and 12th terms = 129 therefore the value of the 11th term is 129/3 = 43.
The sum of the 19th, 20th and 21st terms = 237 therefore the value of the 20th term
is 237/3 = 79.
The difference between the 20th and 11th terms is 79-43 = 36 therefore the common difference is 36/9 = 4.
Using the 11th term gives us 43 = 11 x 4 + a, therefore a = -1.
The AP is therefore -1 + 4n
