Write down in terms of n, an expression for the nth term
of the following sequences:
a) 12
10
8
6
4

14 - 2n

Step-by-step explanation:

a = first term = 12

d = second term - first term = 8 - 10 = -2

nth term = a + (n-1)d

= 12 + (n-1)*(-2)

= 12 + n * (-2) - 1*(-2)

= 12 -2n + 2

= 14 - 2n

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
