Sum of Linear Number Sequence
This calculator deals with a linear number sequence - a set of values where every consecutive one differs by the same amount from the previous one. An example would be 20, 23, 26, 29 - it's a sequence of
4 numbers, with
20 as the initial value,
3 as the difference between successive figures,
29 as the final value and
98 as the sum of all numbers.
A practical example.
We're selling photo storage in the cloud. Customers pay us an amount of money that's directly proportional to the amount of data that they upload -
$1 per 1 Gigabyte. Alice initially uploads
5GB of family photos and then adds
2GB per month. We want to know how much she stores after a year and how much her business is worth to us during that time. Below you'll find a table with all the values and a pre-filled calculator widget.
