High from the ground climbing up first step = 10 cm
High from the ground climbing up sec ond step = 10 + 17.5 = 27.5cm
High from the ground climbing up third step = 27.5+ 17.5 = 45 cm
High from the ground climbing up fourth
step=45 +17.5 = 62.5 cm
High from the ground climbing up fourth step = 62.5 + 17.5 = 80 cm
High from the ground climbing up fourth
step = 80+ 17.5 = 97.5cm
ii. Sequence of height
10, 27.5, 45, 62.5, 80, 97.5
