Even I can see what's happening with the first one:
add 1, then add 2, then add 3, then add 4, etc.
Turn your imagination loose and see what you find. These are not difficult.
describe how each sequence is generated and write down the next two terms:
a) 40 41 43 46 50 55
b)90 89 87 84 80 75
c)1 3 7 13 21 31
d) 2 6 12 20 30 42
