Find an explicit formula for the arithmetic sequence -5,13,31,49

an explicit formula for the arithmetic sequence -5,13,31,49 is   .

Step-by-step explanation:

Here we have an arithmetic sequence -5,13,31,49 . We need to find an explicit formula for the arithmetic sequence  .Let's find out:

Let   be terms of an A.P , common difference is :

⇒

⇒

⇒

⇒

We know that general term of an Arithmetic Progression ( A.P) is :

⇒

So , Here we will have  

⇒

⇒

⇒

Therefore , an explicit formula for the arithmetic sequence -5,13,31,49 is   .

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
