Pola menaik = Increasing pattern If the numbers grow by the same amount each time, the pattern is increasing. 145, 150, 155, 160 grows by 5 each step. Example: 230, 240, 250, 260 grows by 10, because 230 + 10 = 240. Watch out: Numbers that grow by different amounts, like 1, 2, 4, 7, do not form this kind of pattern.
Langkah 2
Pola menurun
Jika nombor berkurang dengan nilai yang sama, pola itu menurun. Contohnya 620, 610, 600 ialah pola nombor menurun sepuluh-sepuluh.
Pola menurun = Decreasing pattern If the numbers shrink by the same amount each time, the pattern is decreasing. 620, 610, 600, 590 goes down by 10 each step. Example: 480, 470, 460 goes down by 10, because 480 − 10 = 470. Watch out: From 600, taking 10 changes the hundreds digit too, giving 590.
Langkah 3
Semak setiap langkah
Perbezaan antara setiap pasangan nombor bersebelahan mesti sama.
Semak setiap langkah = Check every step To be sure there is a pattern, find the difference between every pair of neighbours. 145 to 150 is +5, 150 to 155 is +5 and 155 to 160 is +5. Example: 312, 315, 318: 315 − 312 = 3 and 318 − 315 = 3, so every step is 3. Watch out: Checking only the first pair is not enough; the jump might change later.

Lengkapkan pola = Complete the pattern The question gives 145, 150, 155 and asks for the next number. Work out how much is added each step, then add the same amount to 155. Example: 225, 230, 235, so the next number is 235 + 5 = 240. Watch out: Work out the jump first instead of guessing from the last digit.

Lengkapkan pola menurun = Complete a decreasing pattern The question gives 620, 610, 600, and the numbers keep getting smaller. Work out how much is taken away each step, then take the same amount from 600. Example: 340, 330, 320, so the next number is 320 − 10 = 310. Watch out: Going below a whole hundred means borrowing from the hundreds, so work carefully.
