None of the other answers are correct

4

Step-by-step explanation:

AB + BC = AC

(x + 4) + (2x - 10) = 2x + 1

x + 4 + 2x - 10 = 2x + 1

x - 6 = 1

x = 7

BC = 2(7) - 10 = 4

step-by-step explanation:

this is not a question

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
