How can I create a new column with mutate function in R that is a sequence of values of other columns in R?

I have a data frame that looks like this :

I want to create a column with mutate function of something else under the dplyr framework of functions (or base) that will be sequence from b to c (i.e from 2 to 10 with length the number of rows of this tibble or data frame)

Ideally my new data frame I want to like like this :

How can I do this with R using dplyr ?

library(tidyverse)
n=5
a = seq(1,n,length.out=n)
b = rep(2,n)
c = rep(10,n)
data = tibble(a,b,c)

>Solution :

We may do

library(dplyr)
data %>% 
  rowwise %>%
   mutate(new = seq(b, c, length.out = n)[a]) %>%
   ungroup

-output

# A tibble: 5 × 4
      a     b     c   new
  <dbl> <dbl> <dbl> <dbl>
1     1     2    10     2
2     2     2    10     4
3     3     2    10     6
4     4     2    10     8
5     5     2    10    10
