Answer: 62

Step-by-Step Explanation:

First Term (a) = 7
Common Difference (d) = 12 - 7 = 5
Term to Find (n) = 12th

Therefore, finding the 12th Term :-
=> a+(n-1)d
= 7 + (12 - 1)5
= 7 + (11)5
= 7 + 55
=> 62

Hence, 12th Term of this AP is 62

Answer:27

Step-by-step explanation:

first step:- we have to find d(common difference )of the series.

d = second term - first term

d= 12-7

An= a + (n-1)d

An = 7+ (5-1)

A5 = 7 + 20

A5 = 27 hence fifth term .
