This formula is not in the emath syllabus however I feel that it’s important for u to know it as it’s hard to come up with the nth formula when under stress during an exam
If u wanna know, this formula is only for when it’s being added by a constant number; in this case +7
If the sequence is being multiplied use this formula : nth term= ar^(n-1), where r is the multiplication number and a is the first term
