It’s been a while since I’ve done math like this

So here’s the string of equations given

7+e+2=14

m+3+c=19

r+f+5=29

6+b+l=?

now the intended pattern was for each letter to represent its place in the alphabet making ?=20 but I want to also find the equation that represents those letters as simple variables and finding a correlation between the equations.

so in other words I’m looking for an equation that fits

f(1)=14

f(2)=19

f(3)=29 and so on.

Would it not be f(e) = 5, or f(5) = e?

Is f(4) = 44 or 49?

F(4) would equal 44 in this case since the pattern I'm trying to write an equation for would mean the integer in which the answers increase, increases by 5. So from f(1) to f(2) it increased by 5, f(2) to f(3), 10, so the next step would be f(3) to f(4) increasing by 15 making f(4)=44

Great, I was not sure whether the interval increases arithmetically (5,10,15,20) or geometrically (5,10,20,40)

I can see that too that’s a great point.

f(n)= 2.5*n^2 - 2.5*n + 14

What would it be if it were geometrically? would you and would you be able to provide me with how you cane up with both equations? Thank you
