Step 1 of 4 · Spot the pattern
Find the pattern (the jump between numbers), then continue it.
Step 2 of 4 · Try it
10, 20, ?, 40, 50
Look at two neighbors that AREN'T missing.
jump = +10
Step 3 of 4 · Bigger numbers
940, 960, ?, 1000
Same trick — even with bigger numbers.
jump = +20
Step 4 of 4 · Your turn
