Adam and brianna each made a number pattern. adam's pattern starts with number 3 and follows rule add 6. what are first four terms of adam's pattern?

3 9 15 21

Step-by-step explanation:

3+6=9

9+6=15

15+6=21

or think of it as 3+3+3+3+3+3+3=21

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
