y=5x+20
If you need to you can graph this in Desmos.
y is cost, 5 is price per dog, x is the number of dogs 5 and x times each other. y is total cost.
I hope this helps.
Judging by the way the pattern goes,
1+3=4
4+5=9
9+7=16
16+9=25
25+11=36
Then the next 3 numbers would be:
36+13= 49
49+15=64
64+17=81
The next three numbers are 49, 64 and 81
The pattern is adding 2 to each number. So 3 is added to 1 to make 4. The next number added to 4 would be 5, so on so forth.
