Question 8 of 99 Which of the following BEST completes the sequence below? C3, G7, K11, O15, ___?

S-19  obviously……….but kind of a crappy sequence since you started on C-3——-but then the rest jumped by 4  . 

so shouldn’t you have started with D-4?    why go 3, 4 , 4, 4,  and then one presumes another 4. ?

That would be S19.

S19,  W23, ……?..
