X Is 76 dear

Hope it helps u

76

132–3=129

132–3=129129–5=124

124–7=117

124–7=117117–11=106

124–7=117117–11=106106–13=93

124–7=117117–11=106106–13=9393–17=76

124–7=117117–11=106106–13=9393–17=76The series Is of subtracting prime numbers!

Answer:

Given :

Sequence - 132, 129, 124, 117, 106, 93, X.

To Find :

The value of 'x'.

Solution :

First of all let us know this squence is based on what ?

So, Let's do it,

I think this is based on odd numbers. :D

Let us check,

⇒ 132 + 129 = 261.

⇒ 129 + 124 = 253.

⇒ 124 + 117 = 241

⇒ 117 + 106 = 223.

⇒ 106 + 93 = 199.

⇒ 93 + 17 = 114.

So, Did you find the correct number?

No, My friend actually there is no option of 114.

Let's do this with same method but, We will subtract instead of addition,

Let's do it,

⇒ 132 - 3=129

⇒ 129 - 5=124

⇒ 124 - 7 = 117

⇒ 117 - 11 = 106

⇒ 106 - 13 = 93

⇒ 93 - 17 = 76

Woah! We find the number that is 76 (Option => C).

But My dear let me explain,

In the first try we assume that The given series is of adding prime numbers. But our Assumption goes wrong.

So, then we tried second time and assume that The given series is of Subtraction of prime numbers. But our Assumption goes correct.

Hence,

The series is of subtracting prime numbers!
