Class 10 Mathematics Arithmetic Progressions (AP)Introduction to APs and common difference.Expert

0 reads0 ratings0 helpful

Is the sequence (1,8,27,64,\ldots) an AP?

Answer and explanation

Correct answer: No, the differences are (7,19,37,\ldots)

The consecutive differences are not equal, so it is not an AP. In exams, test constancy of differences, not just the visible pattern.
