Find the common difference of the AP 4,9,14,… If the first term changes to 6 and the common difference remains the same then write the new AP.
Common difference in arithmetic progression is denoted by d . It is the difference between the successive term and its preceding term. So, the common difference in this AP is
⇒ 9 - 4 = 5
If the first term is 6 and common difference is 5,
then new AP is,
⇒ 6, 6 + 5, 6 + 10…
Therefore, the new Ap is as follows
⇒ 6,11,16,21,26,31,36,41,46,51,56,61.....
⇒ 9 - 4 = 5
If the first term is 6 and common difference is 5,
then new AP is,
⇒ 6, 6 + 5, 6 + 10…
Therefore, the new Ap is as follows
⇒ 6,11,16,21,26,31,36,41,46,51,56,61.....
