SUMMARY

The missing number in the provided number sequence pattern is determined through basic arithmetic operations. The sequences presented are: 9 + 1 = 6 + 4, 4 + 5 = 7 + 2, 5 + 8 = 8 + 5, and 1 + 3 = 5 + X. By solving the last equation, X is found to be 1. This assessment question tests the ability to recognize patterns and apply fundamental mathematical operations.

PREREQUISITES
  • Basic arithmetic operations (addition, subtraction, multiplication, division)
  • Understanding of number sequences and patterns
  • Problem-solving skills in mathematical contexts
  • Familiarity with assessment techniques for evaluating logical reasoning
NEXT STEPS
  • Explore advanced number sequence patterns and their solutions

TL;DR
pattern numbers
these are a pattern of number sequence asked in assessment for new employee , what could be the missed number
9 1 6 4
4 5 7 2
5 8 8 5
1 3 5 X

is says the equation could be limited to (addition, subtraction, division and multiplying)

9-6=4-1
4-7=2-5
5-8=5-8
1-5=X-3
X=-1

Is the solution unique?

Here is one

9 + 1 = 6 + 4
4 + 5 = 7 + 2
5 + 8 = 8 + 5
1 + 3 = 5 + X
 
Please refrain from posting questions and answers (!) that could affect decisions in real life.

We don't do it in case of car accidents, so we shouldn't do it in the realm of assessments. Furthermore, we do not solve homework questions, of any kind.

Thank you.
