Answer:
1st term: -3
2nd term: 6
3rd term: 21
4th term: 42
Step-by-step explanation:
This problem is unclear if I need to find the first 4 terms or the 4th term. I'm going to assume both possibilities.
To find the value of a term n, you'd just have to plug in that value n into the equation. When finding the first four terms of a sequence, you have to plug in the numbers 1, 2, 3, 4. When you plug in those numbers, you get those said answers.
1st term: 3(1^2)-6=-3
2nd term: 3(2^2)-6=6
3rd term: 3(3^2)-6=21
4th term: 3(4^2)-6=42
When assessing this problem, it is a geometric sequence with a common multiplier.
