find the missing no 81,87,99,117,141,171​, 207

Step-by-step explanation:

Given:

find the missing no 81,87,99,117,7,171​

To find:

Solution:

• This series is a numerical sequence in which the numbers are arranged orderly and make a sequence.
• The pattern is (x₁,x₂,x₃,x₄,x₅,x₆) are the numbers in the series thus x₁, (x₁+6)⇒x₂, (x₂+12)⇒x₃, (x₃+18)⇒x₄, (x₄+24)⇒x₅, (x₅+30)⇒x₆.
• (x₁,x₂,x₃,x₄,x₅,x₆) is added with the 6 multiplies of (6,12,18,24,30,36).

x₁=81

The first number 81 is added with 6. Thus we get 87, the second number.

81 ⇒87

          ⇒81+6

          x₂⇒87

The second number 87 is added with 12. Thus we get 99, the third number.

     87⇒99

         ⇒87+12

        x₃⇒99

The third number 99 is added with 18. Thus we get 117 the fourth number.

    99⇒117

        ⇒99+18

        x₄⇒117

The fourth number 117 is added by 24. Thus, we get 141, the fifth number.

   117⇒141

          ⇒117+24

         x₅⇒141

The fifth number 141 is added with 30. Thus we get 171, the sixth number.

141⇒ 171

          ⇒141+30

        x₆  ⇒171

The sixth number 171 is added with 36. Thus we get 207, the seventh number.

The next number in the series is 171+36 =207

                                                           x₇= 207

Hence,

The next number in the series is 207.
