145
CXLIX C = 100 XL = 40 IX = 9
Cxlvi (c=100; xl=40; vi=6)
Xl = -10+50 = 40
It is: 40 = XL
146 = CXLVI (C=100; XL=40; VI=6)

XXVII (27 in Roman numerals) added to XL (40 in Roman numerals) equals LXVII, which is 67 in Roman numerals.
145 in Roman numerals is written as CXLV. 'C' represents 100, 'XL' represents 40, and 'V' represents 5.
C = 100 and XL = 40 (10 less than 50) so 140 is CXL
40
XL
