Step-by-step explanation:
Check the picture below, so the distance of the house from the other side is that blue gap.
so, there are 12 inches in 1 foot, so let's just convert all those feet to inches and subtract them.
Answer:
12, 36, 108, 324
Step-by-step explanation:
using the recursive formula and a₁ = 4 , then
a₂ = 3a₁ = 3 × 4 = 12
a₃ = 3a₂ = 3 × 12 = 36
a₄ = 3a₃ = 3 × 36 = 108
a₅ = 3a₄ = 3 × 108 = 324
