Step 1: To find the 1st term, plug in (any variable)n = 1. in the sequence and simplify

[NOTE: Knowing that, n represents the position of a term in the sequence. So change the n values.]

Step 2: To find the 2nd term, plug in n = 2. In the sequence and simplify

Step 3: Take the various n values and substitute in the sequence, till you get the required sequence.
