Question

the sum of 3 concecutive terms of AP is 24 and product of 2 preceding is 55.Find terms​

Answer 1

Answer:

5 , 8 , 11 are the terms,

Let the first term be: a-d

Second term : a

Third term: a+d

Thus sum of AP with common difference d is

3 a = 24

a= 8

Now

Product of first and last term

( a-d ) ( a+d ) = 55

a^2 - d^2 = 55

64 -55 = d^2

d^2 = 9

d = +3 or - 3

So the desired terms are 5 , 8 , 11
