Question

1)Use mathematical induction to prove that
a+ar+ar^2+....+ar^n =ar^n+1-a/r-1
where r! =1 and n>=0
(Hint: first prove it is true for n =0 and n=1 both)​

Answer 1

Answer:

$5 { \frac{5225 \times \frac{ \gamma \beta }{?} }{?} }^{2} \times \frac{?}{?} .5464 \leqslant < 92 > = 344 \geqslant 344 - 4.4$
