Without using any real sequencing formulas...
for the first one, the only real sequence is to add 7. (-5) + 7 = 2... +7 = 9... so it depends on whether -5 is the (0th) term or the (first) term. For our sake, we'll say it's the (0th) term... -5 + (7)(whichever term) = answer. so... for example, the first term is -5 + (7)(1) = 2 second term is -5 + (7)(2) = 9 similar with the second question. |
