Please am new here and I have a question The sum of the first eight terms of the AP logx, logx race to the power of 2 and logx race to the power of 3.....ia

[@waterguy7463]

4×-3=-12 then how did you got 15/4??i got the D as 9/5

[@SangayWangmoB-qh2yp]

It's because he multiplied 3 *4 and then added it with 3 which is the numerator

[@EbotJunior-b9j]

You made a mistake to convert -3¾ to proper fraction is -9/4 not 15/4

[@tambuwalmathsclass]

-15/4 is the correct convertion. -3¾ =-(3¾) =-(15/4) =15/4

[@MulkiOsman-e2i]

Where does 5d come from I'm confused 😕

[@rubyseth1562]

It’s gotten from basically saying T6= a+(6-1)d So that’s now T6=a+(5)d T6=a+5d

[@S_e_v_e_n_t_i_e_n]

Good day sir Why did you say 5d? I'm a bit lost

[@tambuwalmathsclass]

Because one has to add d to get to other terms
