Answer:
1= 1
2=11
3=7
Step-by-step explanation:
subtract 6 from the input so
7-6=1
11-6=5 so input 11
13-6=7
The amount you save is : $119 (usd im so sorry, i tried to do it in £ but i had a hard time with the different currencies.) so, the sale price is : $51 usd
1 + 1 = 2
2 + 2 = 4
4 + 3 = 7
7 + 4 = 11
11 + 5 = 16
16 + 6 = 22
22 + 7 = 29
29 + 8 = 37
sorry that I do not know the equation for this problem...but ur next 3 numbers are : 22,29,37.....so ur answer is D
