## SAT Hardest Problems

## SAT Tips for Numbers and Operations

## Numbers

- Know the properties of even and odd numbers.
- Even numbers: \(\ldots, -6, -4, -2, 0, 2, 4, 6, \ldots , 2n, \ldots\), where \(n\) is an integer.
- Odd numbers: \(\ldots, -7, -5, -3, -1, 1, 3, 5, 7, \ldots, 2n+ 1, \ldots\), where \(n\) is an integer.
- Consecutive integers: \( \ldots, n-1, n, n+1, n+2, n+3 \ldots\), where \(n\) is an integer.
## Number Line

- Consecutive integers: \( \ldots, n-1, n, n+1, n+2, n+3 \ldots\), where \(n\) is an integer.
- Only assume that the tick marks are equally spaced, nothing more.
## Factors, Divisibility, and Remainders

## Fractions and Decimals

- When dealing with fractions, one whole unit = 1.
## Ratios, Proportions, and Percents

- Know the Properties of Proportions.
- Pay attention to units.
## Sequences and Series

- For an arithmetic sequence: \(a_{n}=a_{1}+(n-1)d\).
- For a geometric sequence: \(a_n = a_1 \times r^{n-1}\).
- For an arithmetic series: \(S_n = \frac{n(a_1+a_n)}{2}\).
- For a geometric series: \(S_{n}= a_1 \times \frac{r^n -1} {r-1}, \text{where}\ r\neq 1\).
