Find the 54th term of the arithmetic sequence -7,-23,-39

-855

Step-by-step explanation:

Find the 54th term of the arithmetic sequence -7,-23,-39

The first term is a_1 = -7

we see that the common difference = d = -23 - (-7) = -16

so the formula:  a_n = (n- 1)*d + a_1

a_54 = (54 - 1)* (-16) + (-7)

a_54 = 53 *(-16) - 7 = -848 - 7 =  -855
