The water level as a river recedes after a flood is measured at regular intervals, and its height relative to normal, in inches,
Tems11 [23]

Answer:

<em>-26</em>

Step-by-step explanation:

Given the sequence:

16, 9, 2, –5, ...,

To find:

7th measurement, if the above sequence continues:

Solution:

Let us examine the given sequence first:

First term is 16

Second term = 9

Third term = 2

Fourth term = -5

Difference between 2nd and 1st term = 9 - 16 = -7

Difference between 3rd and 2nd term = 2 - 9 = -7

Difference between 4th and 3rd term = -5 - 2 = -7

We can see that there is a common difference of -7 between each term.

That means, the sequence is in Arithmetic Progression.

whose first term, a=16

Common difference, d=-7

To find:

7th term i.e. a_7=?

Solution:

Formula for nth term of an Arithmetic Progression is given as:

a_n=a+(n-1)d

Let us put n=7

a_7=16+(7-1)\times (-7)\\\Rightarrow a_7=16+6\times (-7)\\\Rightarrow a_7=16-42\\\Rightarrow \bold{a_7=-26}

7th measurement will be <em>-26.</em>
