S = (rL – a) / (r – 1)
Multiplying by r – 1:
(r – 1)S = rL – a
Multiplying out the brackets:
rS – S = rL – a
Collect r terms on the left, and others on the right.
Subtract rL:
rS – rL – S = – a
Add S:
rS – rL = S – a
Factorise the LHS:
(S – L)r = S – a
Divide by S – L:
r = (S – a) / (S – L).

r is the huge sort you multiply with the aid of to get the subsequent term. So multiply 1408 with the aid of a million/4 (2d term), that with the aid of a million/4 ( 0.33 term) and that with the aid of a million/4 lower back. sum of 5 words is first term circumstances (r^5 – a million)/(r – a million) 3 is 6390 ( a million + 0.09/2)^ (2 • 6) the two is as a results of the fact semiannual capacity 2 circumstances a 12 months
