Answer:
The AP is 6,10,14... and the 19th term is 78
Step-by-step explanation:
5th term = a+4d=22 (1)
14th term = a +13d=58 (2)
Subtracting both the terms
9d=36
d=4
Putting value of d in (1)
a+4x4=22
a=22-16=6
19th term = a+18d
=6+18x4
=6+72
19th term = 6+72=78
Therefore, The AP is 6,10,14... and the 19th term is 78
