Step-by-step explanation:

a geometric sequence means that every term is created by multiplying the previous term by a certain constant factor. this factor is called the "common ratio".

so,

6×r = 18

r = 18/6 = 3

and a quick check tells us this works also for the next terms (18×3 = 54, 54×3 = 162), so it is indeed a geometric sequence with common ratio 3.

a0 = 6

a1 = a0 × 3 = 6×3 = 18

a2 = a1 × 3 = a0 × 3×3 = 6×3² = 54

an = a0 × 3^n = 6 × 3^n

so,

f(x) = 6×3^x, x is integer, x >=0

Which number is between 7/11 and 0.75( the 75 is repeating)
AlekseyPX

Convert 7/11 to a decimal value.

7 divided by 11 = 0.636364

Subtract 0.636364 to 0.757576 and divide the difference by 2.

Following the equation, 0.636364 - 0.757576 = 0.121212.

<span>0.121212 divided by 2, the quotient is 0.06 (06 is repeating) </span>
