The arithmetic sequence is the first one.
If ~v = hv1, v2, v3i and ~w = hw1, w2, w3i are vectors and c is a scalar, then
(a) c~v = hcv1, cv2, cv3i
(b) ~v + ~w = hv1 + w1, v2 + w2, v3 + w3i
(c) ~v − ~w = hv1 − w1, v2 − w2, v3 − w3i.

First we put parentheses and in each bracket we put (X) and then we put the signs x² is positive and the 17X before it is a negative q is positive with negative —> negative, and negative before 17X and negative before the 60 —> positive. And then the number that does not have (x) where did it come from, for example 60 came from 20 x 3 or 30 x 2...etc. We can verify this by multiplying the parentheses together and the same number comes out .
Or it can be checked by multiplying the first bracket 3 with x from the second parenthesis comes out 3X and negative 20 from the second parenthesis with X from the first parenthesis and subtract 3X from –20xcomes out –17X .
I hope I helped you^_^
Answer: 1 and 7/8
Step-by-step explanation: In this problem, we have 10/16 divided by 5/15. Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division sign to multiplication and flip the second fraction.
So, 10/16 ÷ 5/15 can be rewritten as 10/16 × 15/5.
Now, we are simply multiplying fractions. To multiply fractions, we multiply across the numerators and multiply across the denominators.

Since the fraction 150/8 is not in lowest terms, we need to divide both the numerator and denominator by 10 to get 15/8.
Since 15/8 is an improper fraction, we can change this to a mixed number by dividing the denominator into the numerator.

Therefore, 10/16 divided by 5/15 = 1 and 7/8.
