A spider is climbing up a wall. During the daytime it climbs 5 cm, but then slips back 2 cm during the night. If it started climbing from the bottom of the wall on the morning of January 30th, on what day would it first reach a height of 74 cm?

Compare these two waves: the blue and orange waves have the same pitch, but the blue wave is louder. the blue and orange waves have the same volume, but the blue wave has a higher pitch. the orange wave has a higher pitch, but the blue wave is louder. the blue wave has a higher pitch, but the orange wave is louder.
