Question

How do you find the nth term for geometric sequences? For example, 3,6,12,24,48.

Answer 1

nth term = ar^(n-1)
here a = first term = 3
and r = common ratio = 6/3 = 2

so nth term of ur sequence is 3*2^(n-1)

Answer 2

the common ratio is the number which multiplies each term to get the next
eg 6 = 3*2, 12= 6*2 eyc

Answer 3

Thanks so much!

Answer 4

yw

Answer 5

Do you know what the formula is for arthmetic sequences?

Answer 6

nth term of an AS = a + (n-1)d
a=first term, d = common difference
example

2 . 4 , 6 8 ....

a = 2 and d = 4-2 = 2

8th term = 2 + (8-1)*2

Answer 7

in an AS terms are of the for a, a+d, a+2d, a+3d ...
