Question 759083
look for the pattern:

if {{{7+8=17}}} => {{{7+8=15}}} and {{{15+2=17}}}......here add {{{2}}}

{{{8+9=20}}}=> {{{8+9=17}}} and {{{17+3=20}}}.....here add {{{3}}}

{{{ 9+10=23}}} => {{{9+10=17}}} and {{{19+4=23}}}.....here add {{{4}}}

next one will be
{{{ 10+11=x}}} => {{{10+11=x}}} and {{{21+5=26}}}.....here add {{{5}}} and {{{x=32}}}

next one will be
{{{ 11+12=x}}} => {{{11+12=x}}} and {{{23+6=29}}}.....here add {{{6}}} and {{{x=29}}}


next one will be
{{{ 12+13=x}}} => {{{12+13=x}}} and {{{25+7=32}}}.....here add {{{7}}} and {{{x=32}}}

so,

{{{13+14=x}}}=> {{{13+14=x}}} and {{{27+8=35}}}.....here add {{{8}}} and {{{x=35}}}
