Question

What is the pattern here?

(1/3) + (1/6) + (1/9) + (1/12) ....

Answer 1

the denominator goes up by 3 each term

Answer 2

What would the common difference be then, because I have to put a number

Answer 3

there is no common different, you are multiplying, not adding to go from one term to the next

Answer 4

it isnt a difference if it is addition

Answer 5

Do youmean the solution to the problem?

Answer 6

in that case you would find the common denominator and solve.

Answer 7

\[\frac{ 1 }{ 3 }+\frac{ 1 }{ 6 }+\frac{ 1 }{ 9 }+\frac{ 1 }{ 12 }\]
\[\frac{ 12 }{ 36 }+\frac{ 6 }{ 36 }+\frac{ 4 }{ 36 }+\frac{ 3 }{ 36 }\]
\[\frac{ 25 }{ 36 }\]
