5.
an Arithmetic Sequence as a rule:
a%5Bn%5D+=+a%5B1%5D+%2B+d%28n-1%29
if a%5B1%5D=-3+ and d=-7

the explicit formula is:
a%5Bn%5D+=+-3+-7%28n-1%29
the 32nd term is:
a%5B32%5D+=+-3+-7%2832-1%29
a%5B32%5D+=+-3+-7%2831%29
a%5B32%5D+=+-3+-217
a%5B52%5D+=+-220

6.
a%5Bn%5D+=+a%5B1%5D+%2B+d%28n-1%29
a%5B1%5D=-9 andd=3

the explicit formula is:
a%5Bn%5D+=+-9+%2B3%28n-1%29


the 32th term is:
a%5B32%5D+=+-9+%2B3%2832-1%29
a%5B32%5D+=+-9+%2B3%2831%29
a%5B32%5D+=+84
