ANSWER

$\boxed {f(n) = 7n - 4}$

EXPLANATION

From the table,

$a_1 = 3$

$a_2 = 10$

There is a constant difference of

$d = a_2 - a_1$

$d = 10 - 3 = 7$

The sequence is therefore an arithmetic progression.

The general formula for the arithmetic progression is

$f(n) = a_1 + (n - 1)d$

We substitute the values into the formula to obtain,

$f(n) = 3+ 7(n - 1)$

We expand the bracket to obtain,

$f(n) = 3+ 7n - 7$

This simplifies to

$f(n) =7n - 4$

Show your steps in evaluating each of the following expressions. The steps count 4 points each, the answer is 1 point.

ioda

The steps in evaluating each of the following expressions is shown below.

<h3>What is an expression?</h3>

An expression can be defined as a mathematical equation which shows the relationship existing between two or more numerical quantities or variables.

<h3>How to evaluate the given expressions?</h3>

15 - 35/7 - 2 + 3 - 4

15 - (35/7) - 2 + 3 - 4 (bracket and division)

15 - 5 - 2 + 3 - 4 (regroup)

15 + 3 - 5 - 2 - 4 (subtract and add)

18 - 11 = 7.

<h3>Expression 2.</h3>

10 + 2(9 - 5) - 16/18

10 + (2 × 4) - 8/9 (bracket and division)

10 + 8 - 8/9 (add)

18 - 8/9 (subtract)

162/9 - 8/9 = 17 1/9 or 154/9.
