Find the formula for the nth term of the arithmetic sequence -39, 61, 161, 261, ...

maksim [4K]

<h3>Given that it is arithmetic</h3>

$d = a_{2} - a_{1} = 61 - ( - 39) = 100$

$a_{n} = a_{1} + (n - 1)d \\ a_{n} = - 39+ 100 (n - 1) \\ a_{n} = - 39 + 100n - 100 \\ a_{n} = - 139 + 100n$

In the data set below, what is the mean absolute deviation?

lbvjy [14]

Add the numbers and divide by 5 to get a mean of 6.4

8 - 6.4 = 1.6

4 - 6.4 = -2.4

7 - 6.4 = 0.6

8 - 6.4 = 1.6

5 - 6.4 = -1.4

Add the absolute value of each: 1.6 + 2.4 + 0.6 + 1.6 + 1.4 = 7.6

Divide by 5 = 1.52
