I'm new to R and I'm trying to create a loop in R with a string `mod` and a variable `x`

my code so far looks like this `m=1` and `b=1` at the start of the code

```
  for (i in 1:5){
  mod = 'mod'
  mod + as.character(m) = b
  m = as.numeric(m)
  m = m+1
  b = (b + 1) * 2
}

```

what I want as an output is:

```
mod1 = 1
mod2 = 4
mod3 = 10

```

Is this possible or am I overthinking this problem?
