Sequences, series and spotting the pattern

Comparison diagram of arithmetic sequence 4, 7, 10, 13 with +3 arrows and geometric sequence 3, 6, 12, 24 with x2 arrows, with nth-term and sum formulas labelled A sequence is an ordered list of terms, while a series is what you get when you add those terms. The notation unu_nun​ means the nth term, and ∑\sum∑ means "add up".
