Input 7, 8, 9, 10, 11
Output 18, ?, 25, ?, ?
Can you help please
Thanks
probably linear
y = m x + b
18 = m (7) + b
25 = m (9)+ b
==============
-7 = -2 m
m = 7/2
25 = 63/2 + b
50 = 63 + 2 b
b = -13/2
so
y = 7x/2 -13/2
now if x = 8 then
y = 7*8/2 - 13/2 = 21.5
if x = 10 then
y = 28.5
if x = 11 then
y = 32
