common multiples of 2 and 3 are 102,108,114,120 .............198
last term is 198
using te formula
last term = first term +(number of terms -1) common difference
198=102+(n-1)6
(n-1)=96/6
n-1=16
n=17
by using the formual
sum of n terms = no. of terms/2 (2first terms + (number of terms -1) d)
u can find the overall sum
last term is 198
using te formula
last term = first term +(number of terms -1) common difference
198=102+(n-1)6
(n-1)=96/6
n-1=16
n=17
