a = a + d(n-1)
n 1
this is the formula for the arithmetic sequence.
the first sequence is arithmetic
an=1+7(n-1)
the second sequence is also arithmetic
an=12+4(n-1)
Expression for nth Term:
a) 1 + 7(n-1)
b) 12 + 4(n-1)
Step-by-step explanation:
The formula for the nth Term of a Linear Sequence = a + i (n-1)
a = Starting number
i = Increment between patterns
n = The number of the Term that you seek
