mothertig's answer shows the basis of what is probably the quickest method, but it would not have worked if the implied previous number had not been zero.
Consider if the series started from twelve, going 12, 19, 26, 33, 40 etc in steps of seven, and you wanted the 11th number, 7 x 11 would give you the wrong answer.
Count the number of intervals (10 if you wanted the eleventh number), multiply that by 7, then add the first number.
