Question

Generalising the given pattern using match sticks as an algebraic expression, nth term denoting the number of match sticks will be .

• A. 3n+3
• B. 3n-3
• C. 4n+4
• D. 4n-4

Answer 1

The correct option is A 3n+3

By comparing each term and the number of match sticks used, we can see a pattern. By generalising the pattern we will get,
So, when n=1
3n + 3 = 3 x 1 + 3 = 6
When n = 2,
3n + 3 = 3 x 2 + 3 = 9.....
