S = 955 This is an arithmetic sequence, and the sum of an arithmetic sequence can be calculated as: S = n/2 x (U1 + Un) U1 is the first term (in this case 91) and Un is the last term (in this case 100). n presents the total number of terms in the sequence There are 10 numbers in this sequence (91, 92, 93, 94, 95, 96, 97, 98, 99, 100) So, the sum is : S = 10/2 x (91+100) = 955
The lowest common multiple of 84 and 96 is 672
Both 84 and 96 are divisible by 12, so 84/96 = 7/8.
What should be the next number in the following series? 100 96 104 88 120 56
12, 24, 36, 48, 60, 72, 84, 96.
