Answer:
a = 
, r = 
Step-by-step explanation:
The sum to infinity of a geometric progression is
; | r | < 1
Thus for first progression
= 6 ( multiply both sides by (1 - r) )
a = 6(1 - r) → (1)
Second progression
= 7 ← multiply both sides by (1 - r² )
2a = 7(1 - r² ) = 7(1 - r)(1 + r) ← difference of squares
2a = 7(1 - r)(1 + r) → (2)
Substitute a = 6(1 - r) into (2)
2(6(1 - r) = 7(1 - r)(1 + r)
12(1 - r) = 7(1 - r)(1 + r) ← divide both sides by (1 - r)
12 = 7(1 + r) = 7 + 7r ( subtract 7 from both sides )
5 = 7r ( divide both sides by 7 )
r =
Substitute this value into (1)
a = 6(1 - ) = 6 ×

Samuel started out with 21 mowed lawns. 7(months) x 3(lawns) = 21
If he mows 3 lawns per month, then he would have to mow lawns for another 3 months. 3 x 3 = 9.
21 + 9 = 30
Although this is one mowed lawn over the objective, any less would not reach 29.
I'm not really sure what the question is asking, so here's two answers:
He would have to mow lawns for another 3 months in order to mow 29 lawns.
Or, he would have to mow 8 more lawns.
