Answer:
B. 47
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
a1 =3 (it is the first term)
We can find the common difference by taking the second term and subtracting the first term
5-3 =2
d=2
n = the term number we are looking for
an = 3 + 2(n-1)
We are looking for the 23rd term so n=23
a23 = 3 +2(23-1)
= 3 +2(22)
= 3+44
= 47
Answer:
She needs 4 more gallons of blue paint than red paint
Step-by-step explanation:
Since the ratio is 3 to 2, 3 + 2 = 5.
The artist needs 20 gallons of purple paint, so 20/5 = 4
The amount of blue and red paint needed is 4x3 to 4x2, or 12 to 8.
She needs 12 gallons of blue paint and 8 gallons of red paint.
12 - 8 = 4
She needs 4 more gallons of blue paint than red paint.
