Carlos and Ana were asked to find an explicit formula for the sequence -10,-4,2,8,...−10,−4,2,8,...minus, 10, comma, minus, 4, comma, 2, comma, 8, comma, point, point, point

Carlos said the formula is f(n)=-10+6nf(n)=−10+6nf, left parenthesis, n, right parenthesis, equals, minus, 10, plus, 6, n.

Ana said the formula is f(n)=-10+6(n-1)f(n)=−10+6(n−1)f, left parenthesis, n, right parenthesis, equals, minus, 10, plus, 6, left parenthesis, n, minus, 1, right parenthesis.

Which one of them is right?

Carlo formula is correct.

Step-by-step explanation:

Given : Carlos and Ana were asked to find an explicit formula for the sequence -10,-4,2,8,...

Carlos said the formula is

Ana said the formula is

To find : Which one of them is right?

Solution :

We put the value of n in both so that we decide which is right.

Carlos said the formula is

Put n=0,

Put n=1,

Put n=2,

Put n=3,

Carlo formula is correct.

Ana said the formula is

Put n=0,

The first value is not correct.

Ana formula is incorrect.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
