Since the two boxes are identical, we know that both of the boxes are of equal weight. Since one box weighs 168 ounces, the other weighs 168 too. So we add them together..
168 + 168 = 336

The total weight in ounces of the nails that Jason bought is 336 ounces.

Find the 75th term of the arithmetic sequence<br> 16, 15, 14,

slega [8]

Answer:

$a_{75}=-58$

Step-by-step explanation:

This is an arithmetic sequence:

$a_n=a_1+(n-1)d$

where d is the common difference and n is the index of any given term.

For the given sequence, the common difference is -1:

$15-16=-1\\14-15=-1$

Knowing both the common difference and the first term, you can write the equation for this sequence:

$a_n=16+(n-1)(-1)$

Then you can use that equation to find the 75th term:

$a_{75}=16+(75-1)(-1)\\a_{75}=16+(74)(-1)\\a_{75}=16-74\\a_{75}=-58$
