First term: a: 5/6
2nd term: 3/2 = 9/6
3rd term: 13/6
4th term: 17/6
a(n+1)=a(n) + 4/6, or a(n+1) = a(n) + 2/3, with a(1) = 5/6

Answer:
C, D
Step-by-step explanation:
The equation factors as ...
(x -3)(x +3) = 0
The value will be zero when a factor is zero. That is, solutions are ...
x = 3 and x = -3 . . . . . matches choices C and D
Answer: 13
Step-by-step explanation:
represent the first integer as x
Since they are consecutive, you can represent the others as x+1, x+2, and x+3.
Write the equation
x + (x +1) + (x+2) + (x+3) = 58
Combine like terms
4x + 6 = 58
Solve for x
4x= 52
x=13
Answer:
7
