Study the given pattern carefully and select the number that can replace the question mark (?) in it.
Fist row → Middle number = (First number + Second number) x 2 – 3 → (5 + 7) x 2 – 3 = 21 Second row → Middle number = (First number + Second number) x 2 – 3 → (8 + 5) x 2 – 3 = 23 Fist row → Middle number = (First number + Second number) x 2 – 3 → (15 + 7) x 2 – 3 = 41
