Maths homework help please :)

Can you tell me what the nth term formula of these sequences is please

10,18,26,34,42
1,5,9,13,17
26,18,10,2,-6

Thank you guys :)

8n + 2
4n - 3
-8n + 34

OK... come on... now you're not even trying at all. These are all just adding or subtracting a constant. A single-digit one, at that. No multiplication, division, exponents, nothing advanced.

t2 - t1 is a formula.

18 - 10 = 8
Now 26 - 18 = 8

Now you get value of d = 8 for next term add 42 + 8 = 50

do as like sequence.

+8
+4
-8

its just the difference between each number ... o.o
and then u can work it out from there... :L
