### `increment`, `decrement`

Sequelize also provides the `increment` convenience method.

Let's assume we have a user, whose age is 10.

```js
await User.increment({age: 5}, { where: { id: 1 } }) // Will increase age to 15
await User.increment({age: -5}, { where: { id: 1 } }) // Will decrease age to 5
```
