Question

2^n+2-2^n+1+2^n=c×2^n.Find the value of C.​

Answer 1

$\huge\underline\bold\red{Answer}$

2^(n+2)=2^n*4

2^(n+1)=2^n*2

So,

By simplifying it

2^n*4-2^n*2=C*2^n

Taking the 2^n common from the LHS, we get is now 2^n(4-2)=C*2^n

2*2^n=C*2^n

From comparison of LHS & RHS

We find the value of: C=2
