Question

120, 80, 40, 45, ?, 5 logic...

Answer 1

it's correct answer is 40 with logic second +third term is equal to first term

Answer 2

Answer:

The required number is 40.

Solution:

Sequence contains the pattern followed by all the terms. The pattern may be same or different across all the terms

The given problem is a sequence where we need to find out the pattern which is nothing but the logic behind.

Method I:

The pattern seems to be the difference of first two terms is the third term.

120 – 80 = 40

Let us consider the required term be x

Similarly, 45 – x = 5

45 – 5 = x

x = 40

Method II:

We can consider other way as : sum of second and third term is the first term.

80 + 40 = 120

Let us consider the required term be x.

Similarly, x + 5 = 45

x = 45 – 5 = 40

Therefore, the number is 40.
