i) −35,−610,−915,−1220,...
It can be observed that numerator is a multiple of 3 and denominator is a multiple of 5, so if we notice they are increasing in same order
So, next four are −1525,−1830,−2135,−2440
ii) −14,−28,−312...
It can be observed, numerator are incremented by one and multiplied by (−1)
and denominator are multiple of 4
So, next four are
−416,−520,−624,−728...
