23. critical thinking lucia knows the fourth term in a sequence is 55 and the ninth term in the same sequence is 90. explain how she can find the common difference for the sequence. then use the common difference to find the second term of the sequence.

Let's call a the first term and d the common difference.

The fourth term is 55:

The ninth term is 90

Subtracting,

common difference of 7

We found the common difference.  Substituting,

Second term

second term of 41

the answer is 375 miles

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
