Lets call the number 'n'
plus means addition
is means the equal sign
so that as an expression would be
n+4=7
Seems to be aritmetic
an=a1+d(n-1) is aritmetic
a1=fist term
d=comon difference
n=which term
a4-a2=2d where d is the common difference
26-14=12
12=2d
6=d
so
a2-6=a1
14-6=8
an=8+6(n-1)
expand
an=8+6n-6
an=6n+2
