Good passwords typically contain a combination of:
The pattern involves differences between consecutive terms:
9 - 7 = 2
13 - 9 = 4
21 - 13 = 8
37 - 21 = 16
The differences follow a sequence: 2, 4, 8, 16... (doubling each time).
Next difference = 16 × 2 = 32.
Next term = 37 + 32 = 69.
If 1/3 of the tank holds 80 litres, we can set up a proportion to find the total capacity of the tank:
1/3 × Total Capacity = 80 litres
To find the total capacity, we can multiply both sides by 3:
Total Capacity = 80 litres × 3
= 240 litres
Now, we can find the quantity of water that 1/2 tank holds:
1/2 × Total Capacity = 1/2 × 240 litres
= 120 litres
