b=1.1; a=[1;5;6] c=a.*b; c=mean(c)

now I want to check if c lies between 6 and 7, if not i want to try b=1.2 and b=1.0 and b=1.3 and b=0.8 and so on decreasing and increasing

Since c is equal to the mean of b*1,b*5 and b*6, hence c = b*(1+5+6)/3 = 4*b. Therefore 6<4*b<7 implies b lies between 1.5 and 1.75 to satisfy your condition. One approach is to no longer decrease b as that won't give you the result. Start with b=1.1, use a do while loop with terminating condition as 6<c<7. in the body of the loop, compute c as you mentioned in the question.
