Question

15,17,20 ,25,33 46,67, find the next series​

Answer 1

Answer:

101

Explanation:

First, let's see the difference between the number and its next number.

➥ 15

➥ 15 + 2 = 17

➥ 17 + 3 = 20

➥ 20 + 5 = 25

➥ 25 + 8 = 33

➥ 33 + 13 = 46

➥ 45 + 21 = 67

67 + ? = next number

The series of difference : 2, 3, 5, 8, 13, 21, ?

We can see a pattern here.

➥ 2 + 3 = 5

➥ 3 + 5 = 8

➥ 5 + 8 = 13

➥ 8 + 13 = 21

The next n. = Sum of two previous n.

The next number = 13 + 21 = 34

Now add 34 to 67

➥ 67 + 34 = 101

101 is the next Number
