Question

the lengths of the sides of a 6-sided polygon are in arithmetic sequence. the length of the shortest side is 3 meters,if the length of the next longer side is 5 meters, what is the length of the longest side?

Answer 1

Answer:

13 m

Step-by-step explanation:

since the sides form an arithmetic sequence, with first term 3, second term 5

then common difference d = 5 - 3 = 2

Add 2 to each term to generate the sequence

3, 5, 7, 9, 11, 13 ← 6 sides of the polygon

longest side = 13 m
