heyy this is the correct value of R

Answer 2

R=7739 is the missing number in the series

7055, 7223, 7393,7565, 7739, 7915,​

Step-by-step explanation:

Given:

7055, 7223, 7393,7565, R, 7915,​

To find:

The missing number R in the series.

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+168)⇒x₂, (x₂+170)⇒x₃, (x₃+172)⇒x₄, (x₄+174)⇒x₅, (x₅+176)-1⇒x₆.
• The numbers (x₁,x₂,x₃,x₄,x₅,x₆) is added with (168,170,172,174,176) consecutively thus forms the series.
• The pattern of this series is the first number x₁ is added with 168 and it forms the second number x₂.

7055 ⇒7223

          ⇒7055+168

           x₂⇒7223

• The pattern of this series is the second number x₂ is added with 170 and it forms the third number x₃.

7223⇒7393

         ⇒7223+170

         x₃⇒7393

• The pattern of this series is the third number x₃ is added with 172 and it forms the fourth number x₄.

7393⇒7565

            ⇒7393+172

           x₄ ⇒7565

• The pattern of this series is the fourth number x₄ is added with 174 and it forms the fifth number x₅.

7565⇒R

           ⇒7565+174

           x₅⇒7739 ⇒R

The next number in the series is R=7739

• The pattern of this series is the fifth number x₁ is added with 176 and it forms the sixth number x₆.

   R⇒7915

          ⇒7739+176

          x₆⇒7915

Hence,

The Missing number in the series is R=7739
