Ok, so find the least common multiplule betwen 4 and 6
4=2*2
6=2*3
LCM=2*2*3=12
12 days from start
5th
12 days fraom that is 12+5=17
the 17th
Since this is an arithmetic sequence, you can conclude that
the addition to the number is constant.
Let x = the number asked
k = constant
number added to the sequence
7 + k = x
x + k = 17
Solve the system of equation:
7 + k + k = 17
7 + 2k = 17
2k = 10
k = 5
Therefore, the missing number is 12 (7 + 5).
2(w+60) + 2w= 520
perimeter of a rectangle = 2(length)+2(width)
length=w+60ft
width=w
perimeter=520ft
520ft=2(w+60)+2w
Answer:
