\log 4, \log \left(2^x+2\right), \log \left(2^{x+2}+1\right)

are 3 consecutive terms of an arithmetic progression then

x

lies between 2 consecutive natural numbers

p

and

q(p < q)

find the value of

(p+q)

View answer and explanation

Correct option: A

The correct answer is A (7) because solving the arithmetic progression condition leads to

2^x = 12

, which implies

x

lies between 3 and 4, hence

p+q = 7
