a. a%5Bn%5D+=+8+%2B+%28n-1%293, or a%5Bn%5D+=+3n+%2B+5 ==> a%5B100%5D+=+305
b. a%5Bn%5D+=+n%5E4 ==> a%5B100%5D++=100%5E4+=+10%5E8
c. g%5Bn%5D=5%2A3%5E%28n-1%29 ==> g%5B100%5D+=+5%2A3%5E99
d. a%5Bn%5D+=+2+%2B+%28n-1%295, or a%5Bn%5D+=+5n+-+3 ==> a%5B100%5D+=+497
e. g%5Bn%5D=1%2A%281%2F2%29%5E%28n-1%29 ==> g%5B100%5D+=+%281%2F2%29%5E99+=+1%2F2%5E99
