The following sequence is a combination of an arithmetic sequence and a geometric sequence:
5; 5; 15; 10; 25; 20; 35; 40;...
4.1 Write down the next 2 terms.
4.2 Calculate T42 - T41
4.3 Determine the sum of the first 50 terms.
4.4 Prove that ALL the terms of this infinite sequence will be divisible by 5.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
