BRAINLIEST AWARD NO.2 A sequence begins with the number 4, and subsequent numbers are determined by taking the previous number, tripling it, and adding six to the product. What is the smallest starting number ao in a sequence whose fifth term is greater than 10,000? Please explain

A whole number first term to render as fifth term a value larger than 10000, should be at least 121

Step-by-step explanation:

The formula is given as recursive since it involves the previous number of the sequence, and defined as:

we also know that the first term is 4

Then in this case, the first five terms are:

So if we want to find the first term in the case that the fifth one is greater than 10,000 using this recursive formula, now we have to start backwards, and say that the fifth term is "> 10000" and what the fourth one is.

Notice that if you have this definition for the nth term, we can obtain from it, what the previous term is to find the general rule:

So the rule is to subtract 6 from he term, and divide the subtraction by 3. Then working backwards:

therefore, the starting first term should be at least about 121 to give a fifth term larger than 10,000

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
