Find the 7th term in the sequence -10,-6,-2,

we are adding 4 each time

10+4 = -6

-6 + 4 = -2

-2+4 = 2

2+4 =6

6+4 = 10

10+4 = 14

14+ 4=18

The 7th term is 18

= 14

This is an arithmetic sequence with n th term

= + (n - 1)d

where d is the common difference and the fist term

d = 2 - (- 2) = - 2 - (- 6) = - 6 - (- 10) = 4 and = - 10, hence

= - 10 + (6 × 4 ) = - 10 + 24 = 14

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
