268 seniors will have driving license in 2018.

Step-by-step explanation:

Look at the attached table:

If we find the ratio  of seniors with driving license to number of seniors in all 4 years we observe that:

For year 2014:

222/341 = 0.651 = 65%

For year 2015:

240/367 = 0.654 = 65%

For year 2016:

199/309 = 0.644 = 65%

For year 2017:

246/382 = 0.644 = 65%

We can observe that about 65% of the total seniors own a driving license.

For year 2018  there were 413 total seniors. So around 65% of 413 would own a driving license.

Therefore 65% of 413

= 0.65*413 = 268.45

By rounding off we get 268 seniors will have driving license in 2018.
