To find: 10th common term between the APs

Common difference of 1st series = 4

Common difference of 2nd series = 5

LCM of common difference will give us a common difference of new series

⟹ 5 × 4

⟹ 20

The first term of new AP will be 11, so the 10th = term of this series is

⟹ 11 + 20 × 9

⟹ 191
