Explanation:
3, 7, 11, 15, 19
3 + 4 = 7
7 + 4 = 11
so on
1. the next two numbers after 19
so
19 + 4 = ?
and
? + 4 = ???
2. a = nm + c
m is change between one value to another
c is the starting number
m = 4 as 4 is what the sequence changes by
c = 3 as 3 is the first number
put into a = nm + c
a = n? + ?
3. find the 50th term
n represents the term so put 50 where n is then complete equation
