Question

What is the 11th term of the sequence: 7, 13, 19, 25, ....

Answer 1

Adds 6 each time so the nth term rule is
6n+1
the +1 because you take away the amount you add by from the first term
The substitute 11 into this so
6x11=66
66+1=67
11th term is 67

Answer 2

pattern is adding 6

so the 11th would be 67
