Question

Look at the patterns and find the next number in the pattern.

• A. 44
• B. 28
• C. 16
• D. 40

Answer 1

For the first pattern, numbers given are $10,20,30$
To find next pattern, let us analyse the numbers through a number line.

From number line, we can see that:
$10+10=20$
$20+10=30$
∴ We are adding 10 to a number to get the next number in the series.
So, new number will be $=30+10=40$

For the second pattern, numbers given are $7,14,21$
To find next pattern, let us analyse the numbers through a number line.

From number line, we can see that:
$7+7=14$
$14+7=21$
∴ We are adding 7 to a number to get the next number in the series.
So, new number will be $=21+7=28$


For the third pattern, numbers given are $4,8,12$
To find next pattern, let us analyse the numbers through a number line.

From number line, we can see that:
$4+4=8$
$8+4=12$
∴ We are adding 4 to a number to get the next number in the series.
So, new number will be $=12+4=16$

For the fourth pattern, numbers given are $11,22,33$
To find next pattern, let us analyse the numbers through a number line.

From number line, we can see that:
$11+11=22$
$22+11=33$
∴ We are adding 11 to a number to get the next number in the series.
So, new number will be $=33+11=44$
