कौन सा अनुक्रम सामान्य अंतर (0.75) वाली समांतर श्रेणी है?
Which sequence is an AP with common difference (0.75)?
#ap
#decimal_sequence
#identify_ap
A (1,1.5,2.25,3)
B (4,3.25,2.5,1.75)
C (0.75,1.25,1.75,2.25)
D (2.5,3.25,4,4.75)
Explanation opens after your attempt
Correct Answer
D. (2.5,3.25,4,4.75)
Step 1
Concept
In that option, each step increases by (0.75). In exams, use consecutive difference as the test even with decimals.
Step 2
Why this answer is correct
The correct answer is D. (2.5,3.25,4,4.75). In that option, each step increases by (0.75). In exams, use consecutive difference as the test even with decimals.
Step 3
Exam Tip
विकल्प में हर बार (0.75) की वृद्धि है। परीक्षा में दशमलवों में भी लगातार अंतर को ही कसौटी बनाएं।

अनुक्रम \(0.2,0.02,-0.16,-0.34,\ldots\) का सामान्य अंतर क्या है?
What is the common difference of \(0.2,0.02,-0.16,-0.34,\ldots\)?
#ap
#decimal_sequence
#common_difference
A (-0.18)
B (0.18)
C (-0.22)
D (0.02)
Explanation opens after your attempt
Correct Answer
A. (-0.18)
Step 1
Concept
(0.02-0.2=-0.18), and the same difference continues. In exams, align place values when subtracting decimals.
Step 2
Why this answer is correct
The correct answer is A. (-0.18). (0.02-0.2=-0.18), and the same difference continues. In exams, align place values when subtracting decimals.
Step 3
Exam Tip
(0.02-0.2=-0.18) और आगे भी वही अंतर है। परीक्षा में दशमलव घटाते समय स्थान-मूल्य मिलाएं।

अनुक्रम \(0.6,1.05,1.50,1.95,\ldots\) का सार्व अंतर क्या है?
What is the common difference of the sequence \(0.6,1.05,1.50,1.95,\ldots\)?
#ap
#decimal sequence
#common difference
#hard
A (0.35)
B (0.40)
C (0.45)
D (0.50)
Explanation opens after your attempt
Step 1
Concept
(1.05-0.60=0.45) and (1.50-1.05=0.45). Adding zeros makes decimal subtraction safer.
Step 2
Why this answer is correct
The correct answer is C. (0.45). (1.05-0.60=0.45) and (1.50-1.05=0.45). Adding zeros makes decimal subtraction safer.
Step 3
Exam Tip
(1.05-0.60=0.45) और (1.50-1.05=0.45) है। दशमलव में शून्य लगाकर घटाना सुरक्षित है।
