Question
Work out the first four terms of these sequences.
Given: The first term is 22, and the term-to-term rule is to:
- add 1,
- add 3,
- add 5,
- …
Solution
To work out the first four terms of the given sequence, we start with the first term, which is 22.
To find the second term, we apply the term-to-term rule, which is to add 1 to the previous term. So, we add 1 to 22, giving us 23 as the second term.
For the third term, we add 3 to the previous term, which is 23. This gives us 26 as the third term.
Finally, for the fourth term, we add 5 to the previous term, which is 26. This gives us 31 as the fourth term.
Therefore, the first four terms of the sequence are 22, 23, 26, and 31.
