cans = \( \frac{8 \text{ gallons}}{2 \text{ gallons}} \) = 4


5

What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?

68% Answer Correctly
33
31
38
30

Solution

The equation for this sequence is:

an = an-1 + 2(n - 1)

where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:

a6 = a5 + 2(6 - 1)
a6 = 21 + 2(5)
a6 = 31
