6. Arithemetic Sequences
Sign In
Start by writing the sequence formed by the sum of the numbers in each roll. Then, inspect differences between the consecutive terms of the sequence.
Sequence: 2, 5, 8, 11
Is the Sequence Arithmetic? Yes.
Explanation: See solution.
Let's count the dots on each die and write down the sum of the dots. These numbers will then form our sequence.
In order to determine if it is an arithmetic sequence, we have to inspect the differences between consecutive rolls.
Since the differences are all the same and equal to 3, the given sequence is arithmetic.
