See, its 90/-7.2
So, first multiply and divide by -1 so the equation doesn't get affected
Then it comes,
= -90/7.2
Now remove the point and multiply with 10
= 900/72
Thereofore, the resulting answer would be 12.5
4+7=11
11/2=5.5
round to the nearst whole number
The two numbers would be 29.5 and 40.5... hoped this helped you!!
F(1) = 7
f(2) = 7 + 6 = 13
Recursive formula => f(n + 1) = f(n) + 6
Next term = 31 + 6 = 37.
