2x-10=2. (Answer=6)
2x=12 (you move the -10 to the other side of the equation to make it positive)
Then you divide by 2
2x divided by 2 equals x 12 divided by 2 is 6
So your number is 6. x=6
And you can check this by redoing the equation but putting 6 instead of x
2(6)-10=2
12-10=2
2=2
This equation is true therefore, your unknown number is 6

Answer:
2, 6, 12, 20, 30
Step-by-step explanation:
To find the first 5 terms, substitute n = 1, 2, 3, 4, 5 into the rule
a₁ = 1² + 1 = 1 + 1 = 2
a₂ = 2² + 2 = 4 + 2 = 6
a₃ = 3² + 3 = 9 + 3 = 12
a₄ = 4² + 4 = 16 + 4 = 20
a₅ = 5² + 5 = 25 + 5 = 30
