Answer:
C .26
Step-by-step explanation:
Because the common difference is d=7
To get the common difference(d),you can simply subtract
The second term(a2) by the first term(a1)
( a1 is 5 ) (a2 is 12)
a2-a1
12-5
d=7
add the common difference d=7 to first term(a1) to get the second term
5+7=12
12+7=19
19+7=26
5,12,19,26
