Question

Choose the missing number in the 1pattern. 14, 15, 17, _, 24, 29​

Answer 1

20

Explanation:

each time a consecutive number is added

14+1=15

15+2=17

17+3=20

20+4=24

24+5=29

Answer 2

Answer: 20

Explanation:

We will find a pattern within these numbers. Let x be the missing numbers. You can see that there is a pattern in the subtraction, with each term being distracted with n (1st and 2nd term by 1, 2nd and 3rd term by 2, etc).

15 - 14 = 1

17 - 15 = 2

x - 17 = 3

24 - x = 4

29 - 24 = 5

Then, we can solve one of these equations for x.

x - 17 = 3

x = 20
