what is the 15th term in the sequence:

3, 12, 48, 192, 768, . . ?

what is the 15th term in the sequence

3072

Step-by-step explanation:

3,12,48,192,768,3072 i did this

Ok so see each time 3 is multiplied by 4^(n-1) so at first it’s:

3.4^0= 3

Then it’s 3.4^1= 12

And so on.

So for the 15th term we just have to replace n by 15 so :

3.4^(15-1)

3.4^14= 805306368

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

its 50 miles away from the starting point
