Will the tree be taller than the highest part of the fence 5 years after it is planted?

The height of the tree 5 years after it is planted.
#sn = (a(1-r^n))/(1-r)#

#sn = (42(1-0.95^5))/(1-0.95)#

#= 190.02#

The sum is #190.02# cm + the initial height 86 cm = 276

The height of highest part of the fence .
#an = a^1+(n-d)d#
#a30 = 1.4 + (30-1)xx0.04#

= 2.56 meters
