Answer 1

First Problem Answer is "D"
Sequence is plus one, multiply by 4, add one, ect.

Second Problem answer is "A"
minus 3, plus 4, plus 1, minus 3, plus 4, plus 1

Answer 2

The first series follows the pattern:
Add one, multiply 4, add one, multiply 4 and so on.

So the next number is 53*4 = 212

The second series needs some explanation:
Let the first number be a and the second be b. The pattern is like this.

a, b, a + 1, a + 2, b + 2, a + 3, a + 4, b + 4...

The given series is 10, 7, 11, 12, 9, 13, 14...

Here a = 10, b = 7

The series can be rewritten as:
10, 7, 10 + 1, 10 + 2, 7 + 2, 10 + 3, 10 + 4

7 + 4 = 11 is obviously what follows.

Answer 3

2 +1=3 3X4=12 12+1=13 13X4=52 52+1= 53 53X4=212

10-3=7 7+4=11 11+1=12 12-3=9 9+4=13 13+1=14 14-3= 11

Answer 4

The answer to the first question is 212 b/c your numbers have a pattern, they increase by one and get multiplied by 4. 53 got increased by one already then all u do is multiply it by 4 which equals 212.

For the Second one it gets decreased by three then it increases by four then it goes up by one. 12 subtract 3 equals 9 and 9 + 4=13 and 13+1=14 and 14-3=11.

Answer 5

212
(2+1=3,3*4=12,12+1=13,13*4=52,52+1=53,so 53*4=212)
11
(the series is hopefully this 10 7 11 12 9 13 14 11 15 16 13...)
hope these r correct

Answer 6

2 3 12 13 52 53 ___:
