Find a formula for a geometric sequence that begins with 7, 35, 175,...

b

Step-by-step explanation:

a = 7

r = 35/7 = 5

a × r^(n-1)

7 × 5^(n-1)

b bn = 7 (5)^ (n-1)

Step-by-step explanation:

First we need to find the ration

Take the second term and divide by the first term

35/7 = 5

The formula for the sequence is given by

an = a0 (r) ^(n-1)

where a0 is the first term, r is the ratio

an = 7 (5)^ (n-1)

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
