Now, make a formula on your own. Write a few number machines as examples using that formula. Challenge your classmates to figure it out!
Solution:
Do as directed.
Question 2.
Where would design C appear for the nth time? Class 7
Solution:
Design C will appear nth time at 3nth place. That is, it will appear at 3rd, 6th, 9th, ... places.
Question 3.
Similarly, find the formula that gives the position where the other Designs appear for the nth time. Class 7
Solution:
Design A will appear at 1st, 4th, 7th and so on places. So, it will appear nth time at 1 + (n - 1) × 3 = 1 + 3n - 3 = (3n - 2)th place.
Design B will appear at 2nd, 5th, 8th and so on places. So, it will appear nth time at 2 + (n - 1) × 3 = 2 + 3n - 3 = (3n - 1)th place.
