Question

Three numbers a, b and care in between 2
and 18 such that 2, a,b are in arithmetic
progression and b,c, 18 are in geometric
progression. If a+b+c=25, then the value of
C-a is​

Answer 1

Answer:

c-a= 7

Step-by-step explanation:

a= 5, b= 8, c= 12

we get18b=c^2

then possible value of b is only 8

so c= 12

and we know b+2= 2a

10= 2a

a= 5

c-a= 12-5= 7
