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.
