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

Step-by-step explanation:

This is an arithmetic sequence:

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

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

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

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

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

answer: 1 + 1 = 11
