we created a list named $\text{'}$ student$\_$info' with elements: "John" $,25,$ c$(90,85,88).$

student$\_$info $<-$ list$("$john$",25,$ c$(90,85,88))$

If we want to modify the third element to include a new grade, e$.$g$.,$ add $95$ to the existing grades how we will do that in R programming? how we will write down R code for that?
