Generalise the given pattern of match sticks and express it in algebraic form.Open in App
Solution
The correct option is B 5n + 1
By comparing each term and the number of match sticks used, we can see a pattern. By generalising the pattern we will get,
When n = 1,
5n + 1 = 5 x 1 + 1 = 6
When n = 2,
5n + 1 = 5 x 2 + 1 = 11...
