Solve for x
x=1+13+12+13+12+....∞
1+13=43=1.333. the value of x will be slightly lesser than 1.333 as the denominator keeps increasing
Look at the options
Option a=51.7>2 .this can never be the answer
Option b=11.7<1. this also can never be the answer
Option c=31.4>2. this cannot be the answer
Option d=2.51.7 which is the correct answer
Option e=2, which can never be the answer
