A sequence grows by a fixed amount: 100, 120, 140, 160. What is the value 2 steps after the last term shown?
A220
B180
C140
D224
E200
Worked solution
Linear growth: add the constant yearly amount × the number of years. The correct answer is 200. Traps to avoid: 220 comes from the "one step extra" error; 180 comes from the "one step short" error; 140 comes from the "from start not last" error; 224 comes from the "treated as percent" error.
