Suppose each license plate in a certain state has one digit, followed by four letters, followed by one digit. The letters F, 0, S, and X and the digit 0 are not used. So, there are 22 letters and 9 digits that are used. Assume that the letters and digits can be repeated. How many license plates can be generated using this format?​

If a license plate consists of 3 letters followed by 3 digits and having at least one digit or letter repeated .. How many outcomes are there? 26 * 26 * 10* 10 * 10 ..

Step-by-step explanation:

the answer is 175.4379

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
