Convert result of the previous step from base 10 to base 7.

Step 1: convert 1 from base 21 to base 10

To start the calculation, let d is the number in each digit and n is the exponent of the number in that digit. Therefore, the steps can be shown in the following table.

Exponent (n)	Digit (d)	d x 21ⁿ	Cumulative sum
0	1	1 x 21⁰	1

From the table above, it can be written as a conversion formula as:
(1 × 21⁰)

Then calculate the sum of all the cumulative sums we get:
