If a
=
2 and an+1
(an)2 + 1 then find the value of a4.
Hel quickly!!!

Same length is comparing because it’s saying its the same and not different

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

The answer is 49/16 or 3 1/16
