Maths · Arithmetic and Geometric progressions

is it an AP? If yes, then what is it's common difference?

\( 1^{2}, 5^{2}, 7^{2}, 73 \dots \dots \dots \) is it an AP? If yes, then what is it's common difference?

  • A. No
  • B. Yes, \( d=15 \)
  • C. Yes, \( d=24 \)
  • D. Yes, \( d=25 \)

Step-by-step solution

The given terms are 1^2=1, 5^2=25, 7^2=49, and 73. The differences are 25-1=24, 49-25=24, 73-49=24, so it is an arithmetic progression with common difference 24.
