Answer:
every term has an even factor
Step-by-step explanation:
One of the two factors of the n-th term will be even.
- for n odd, n+1 is even
- for n even, n+2 is even
If the number has an even factor, it is an even number. Every term of the sequence has an even factor, so every term will be even.
( - 45, 0)
to find the x-intercept let y = 0 in the equation
x = 0 →
x = - 15
multiply both sides by 3
x = 3 × - 15 = - 45
x-intercept = ( - 45, 0)
