1st week= 20 walls
2nd week= 20+20=40 walls
3rd week= 20+20+20=60 walls
4th week= 20+20+20+20=80 walls
Therefore, in 4 weeks 80 walls in total will be painted
Answer:
Correct answer: q = 4
Step-by-step explanation:
Given:
3, 12, 48, 192, .....
First term b₁ = 3
Second term b₂ = 12
Third term b₃ = 48
Fourth term b₄ = 192
Common ratio or quotient is:
q = b₂ / b₁ = b₃ / b₂ = 12 / 3 = 48 / 12 = 4
q = 4
