Answer 2

Given:

A sequence: 1, 2, 4, 7, 12, 20, 33

To find:

The next number in the sequence

Solution:

The next number in the sequence is 54.

We can find the number by following the given steps-

We know that the given sequence is based upon a pattern in which a number is formed by adding two previous numbers and 1.

The sequence is as follows-

1, 2, 4, 7, 12, 20, 33

Each of these numbers is formed by adding the last two numbers and 1.

1=0+1

2=0+1+1

4=2+1+1

7=4+2+1

12=7+4+1

20=12+7+1

33=20+12+1

Similarly, the next term would be obtained by adding 33, 20, and 1.

Let the next term be X.

X=33+20+1

X=54

Therefore, the next number in the sequence is 54.
