Question

Here are figures 1-3 of a pattern.

Answer 1

The total number of tiles to be used in figure 4 is 12.

• There are two piles of tiles in every figure.
• The first figure has 2 tiles in its first pile and 1 tiles in the second pile.
• The second figure has 4 tiles in its first pile and 2 tiles in the second pile.
• The third figure has 6 tiles in its first pile and 3 tiles in the second pile.
• The pattern followed here is that the next figure has 2 more tiles in its first pile than that of the previous figure and 1 more tile in its second pile than that of the previous figure.
• This is a sequence.
• Following this pattern, the fourth figure will have 8 tiles in its first pile and 4 tiles in its second pile.
• Thus, the fourth figure will have a total number of tiles equal to 12.
