Find the 10th term of this sequence..

Question

anonymous · Answer

$$\frac{ 1 }{ 16 },\frac{ 1 }{ 4 },1,4$$

nincompoop · Answer

$$a_n=a_1+(n-1)d$$
a1 is the first term of the sequence
d is the common difference
n the number of term to find

nincompoop · Answer

but without looking at the formula, notice how things are multiple of 4 to the right, and division of 4 if you want to go to the left. 
to the right, after 4 is 4x4 = 16, then 16x4 =64 and so on…

anonymous · Answer

yes multiple of 4 both, but what would be the 10th sequence?

anonymous · Answer

You can use the formula she posted or keep multiplying 4 until you get to the 10th

anonymous · Answer

so multiply 64 by 4?

anonymous · Answer

Yea, keep multiplying until you get to the 10th term and if i did it correctly, the 10th term would be 24384

anonymous · Answer

thank you

You are welcome! Btw, a little correction, this is a geometric sequence not arithmetic so you can't use that formula, you have to use the geometric formula. :) Hope I helped
