Find the common difference of the arithmetic sequence shown. 1/4, 3/8, 1/2, ...

a) 1/16
b) 1/8
c) 1/4

Answer 1

the common differnence is obtained by subtracting one term from its next term.

in a arithmetic sequence the difference id the same for all terms

so you could subtract 3/8 - 1/4
or you could subtract 1/2 - 3/8

you will get the same in each case - that is the answer

Answer 2

So 1/8, thank you! :3
