Question

The first street light wil be on fifth house pavement and the fourth of the seventeenth house pavement

Indicate first 4 of the number sequence in this pattern in terms of the number of the houses when the street light is positioned and find the first constant difference

Answer 1

Explanation:

The pattern described is a sequence of street light positions on house pavements. The position of the street lights seems to follow a pattern where the first light is placed on the fifth house pavement, and subsequent lights are placed on every seventeenth house pavement. Let's analyze this pattern:

1. First position: 5th house pavement

2. Second position: 5 + 17 = 22nd house pavement

3. Third position: 22 + 17 = 39th house pavement

4. Fourth position: 39 + 17 = 56th house pavement

So, the first four positions of the street lights are on the 5th, 22nd, 39th, and 56th house pavements.

To find the constant difference between the positions of consecutive street lights, we can subtract the positions of the street lights:

Constant difference = 22 - 5 = 17

The constant difference between consecutive positions of the street lights is 17 houses.
