Answer: 137 + 4(n-1)
Step-by-step explanation:
137 + 4(n-1)
Okay, let's test this starting with week 1:
137 + 4(1-1)
137 + 4*0
137, which is correct because she starts with 137.
Week 2:
137 + 4 (2-1)
137 + 4 * 1
137 + 4
141
Alright, let's see if it is correct if we do week 5:
137 + 4 (5-1)
137 + 4(4)
137 + 16
153
To know that 153 is right we could do 137 + 4 + 4 + 4 + 4, which equals 153.
