Math quiz helps us to enhance brains neural network.
1 / 20
1) Which figure is symmetrical along the vertical axis?
(C) is symmetrical on both vertical and horizontal axes.
2 / 20
2) What comes next in this pattern? 81, 64, 49, 36, ?
These are square numbers in descending order:9², 8², 7², 6² → next is 5² = 25
3 / 20
3) What comes next in the pattern? 1, 2, 4, 7, 11, ?
+1, +2, +3, +4… → 11 + 5 = 16
4 / 20
4) Which of the following shapes has exactly one line of symmetry?
An isosceles triangle has one line of symmetry — down the middle.
5 / 20
5) Which number completes the pattern? 1, 4, 9, 16, ?
These are perfect squares: 1², 2², 3², 4²… → 5² = 25
6 / 20
6) Which comes next? 🔷🔷🔶🔷🔷🔶🔷🔷 ?
Every third shape is 🔶. Others are 🔷.
7 / 20
7) How many times does a regular octagon 🛑 look the same in a full rotation?
A regular octagon has 8-fold rotational symmetry (every 45°).
8 / 20
8) Which letter has a vertical line of symmetry?
Letter A is symmetrical along the vertical axis.
9 / 20
9) Which shape comes next in the pattern? 🔺🔺🔵🔺🔺🔵🔺🔺 ?
Two 🔺 followed by one 🔵 repeats.
10 / 20
10) What comes next in the sequence?
Z, W, T, Q, ?
Pattern moves backward skipping two letters:Z → W → T → Q → O
11 / 20
11) What is the next number in the pattern? 1, 4, 9, 16, 25, ?
These are square numbers: 1², 2², 3², 4², 5², 6² = 36
12 / 20
12) How many lines of symmetry does a regular triangle (equilateral) 🔺 have?
An equilateral triangle has 3 lines of symmetry
13 / 20
13) What comes next in this pattern? 100, 90, 80, 70, ?
The pattern decreases by 10 each time. 70 − 10 = 60
14 / 20
14) What comes next in the pattern? ⬤⬤◯⬤⬤◯⬤⬤ ?
Two ⬤ followed by one ◯ repeats.
15 / 20
15) Which shape does not belong in this group? ⚫ 🔵 ⚫ 🔵 🟥
⚫ and 🔵 are circles; 🟥 is a square — different shape.
16 / 20
16) What comes next in the sequence? Z, X, U, Q, ?
Z (−2) → X (−3) → U (−4) → Q (−5) → O (−6)
17 / 20
17) What comes next in the pattern? 32, 16, 8, 4, ?
The pattern multiplies by 2 each time: 2×2 = 4, 4×2 = 8, etc.
18 / 20
18) What comes next in the pattern? 2, 5, 10, 17, ?
Pattern adds consecutive odd numbers:+3, +5, +7, +9 → 17 + 9 = 26
19 / 20
19) What comes next in the pattern?
A, C, F, J, O, ?
+2 (A to C), +3 (C to F), +4 (F to J), +5 (J to O), so next is +6 → O + 6 = T
20 / 20
20) Which letter comes next in the pattern? M, N, O, P, ?
This is a regular alphabetical sequence
