7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a

2(x - 7)(x - 1)

That can be factored to (x - 2)(x - 1)

The sequence follows this pattern: you square the number, then add 2 to the result, then subtract one from that result; then you repeat. If you check, you will see that 1 squared is 1; 1 plus 2 is 3; 3 minus 1 is 2; 2 squared is 4; 4 plus 2 is 6; 6 minus 1 is 5; and 5 squared is 25. So, the next term would probably be 25 plus 2, or 27.
