Luigi and his family are discussing how to pay for his college education. The cost of tuition at the college that Luigi wants to attend is
$12,000 per year. Luigi's parents will pay 50% of the tuition cost every
year, and Luigi's will pay the rest. Luigi has four years to save enough
money to attend his first three years of college. What is the minimum
amount of money he should save every month in order to reach his goal?

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

the answer is 1,118,210 lol

you got this ; }
