Question
Write down the first three terms of this sequence. (2)First term is 5. Term-to-term rule is multiply by 3 then subtract 8. First term is __________ Second term is __________ Third term is __________5, 7, 134, 7, 81,9, 1413, 7, 5
Solution
First term is 5. To find the second term, we multiply the first term by 3 and then subtract 8. So, 5 * 3 = 15. 15 - 8 = 7. So, the second term is 7.
To find the third term, we multiply the second term by 3 and then subtract 8. So, 7 * 3 = 21. 21 - 8 = 13. So, the third term is 13.
So, the first three terms of the sequence are 5, 7, and 13.
