# Check whether the following sequences are in A.P. or not? {eq}2,4,8,16,... {/eq}

## Question:

Check whether the following sequences are in A.P. or not? {eq}2,4,8,16,... {/eq}

## Arithmetic Progression:

Let a and d be real numbers. Then the numbers of forms \, {eq}a, a + d, a + 2d, a + 3d,... {/eq} are said to form Arithmetic Progression denoted by A.P. The number 'a' is called the first term and number 'd' is called the common difference.
