Question

Ginen :a=18, b=-3, c=2
ii) a= (-20),b=-1,C=-1
Verity that a = (b C) & (a+b) = (0-0) for
each of the above stated values of asb
and c​

Answer 1

Answer:

Given a,b,c are three numbers between 2 and 18 and a+b+c=25 ...(i)

2,a,b are consecutive terms of A.P, then

so we can write , a= (b+2)/2 ...(ii)

also given b,c,18 are consecutive terms of a GP

so it implies c^2 =18b...(iii)

From equations (i), (ii) and (iii), we get

b=8 and 32 , since b is between 2 and 18 , therefore taking b=8

and then taking the value of b and putting it in other 2 equations we get the values of a=5 and c=12
