In a geometric sequence, a4=54 and a7=1458. what is the 12th term?
a. 5,616
b. 354,294
c. 14,350,365
d. 234,812,358

Answer-

Solution-

If there are 2 terms of a Geometric Sequence and where (n > k), then

where, r = common ration of the G.P.

Here,

Putting in the equation,

Again putting the values in the equation,

(-1,-0.5)

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
