Answer:
67.9 kg
Step-by-step explanation:
The given in the problem forms an arithmetic sequence.
Where a1 = 56.7 kg
a2 = 59.5 kg
and a3 = 62.3 kg
common difference
= a2 - a1 = a3- a2
= 59.5 - 56.7 = 62.3 - 59.5
= 2.8 kg
Formula for the nth term of an arithmetic sequence
an = a1 + (n-1)d
Target weight = a5
a5 = 56.7 + (5-1) 2.8
a5 = 56.7 +4(2.8)
a5 = 56.7 + 11.2
a5 = 67.9 kg
