I honestly don't know umm try yes
Step-by-step explanation:
2/5, the formula is art over swimming, 16/40, then simplify 2/5
Answer:

it seems like the first term is -64, so lets write the formula accordingly:
a_n = a1(r)^(n-1)
where 'n' is the number of terms
a1 is the first term of the sequence
'r' is the ratio
the ratio is
because -64 *
= 16 and so on...
the explicit formula is :
= 
5.6 is the correct answer because 1.3 +4.3 would be 5.6 so the next one in the sequence is 9.9
1/2+1/3=
3/6+2/6=5/6
The answer is 5/6.
