Find the first five terms of each sequence. a) a_1 = 2, a_n + 1 = a_n + 3

b) a_1 = ­-4, a_n + 1 = a_n + n^2

Average acceleration: i have no idea how to do this.

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
