I have an array of objects that contains the name and marks of students. like below

I need to calculate the 'average' marks each student has and compare the 'average' marks to get the top student. I am trying like below, I am not getting what am I missing?

```js
var Students = [
  {
    name: "Bob",
    marks: [78,80,89,90,68]
  },
  {
    name: "Alin",
    marks: [87,60,59,70,68]
  },
  {
    name: "bikash",
    marks: [82,60,79,60,80]
  }
];

for (let i = 0; i < Students.length; i++){
  var average = Students[i].reduce((total, next)=> total + next.marks) /2 
}

console.log(average)
```

I need to have average marks of each students to compare the results of All students
