If the investment vehicle they choose to invest in claims to yield 7% growth per year, how much should they invest today? Give your answer to the nearest one thousand dollars. Ricardo’s parents want to have $100,000 saved up to pay for college by the time Ricardo graduates from high school (16 years from now).Equation 1: a5 6, so 6 a1r4, solving for a1 we get a1 6 r4.
We will need to solve a system of equations using both given terms. The sequence above shows a geometric sequence where we multiply the previous term by 2 to find the next term.
Solution This time we have two unknowns, the first term and the common ratio. Geometric sequences are sequences where the term of the sequence can be determined by multiplying the previous term with a fixed factor we call the common ratio. common difference (f) Geometric Sequence. Use a geometric sequence to solve the following word problems. Find the nth term rule for the geometric sequence in which a5 6 and a13 1536. definition: an a1 + f × (n-1) example: 1, 3, 5, 7, 9 11, 13.
