Figure 12.2.1.Its bcoz, (Ref=n/2) the sum of any 2 terms of an AP is divided by 2 gets it middle number. example, 3+6/2 is 4.5 which is the middle of these terms and if you multiply 4.5x2 then u will get 9! ( 1 vote) Upvote. Flag.An arithmetic sequence, we would be adding or subtracting the same amount every time, but we're not. Here, from 500 to 700, we grew by 200, and then from 700 to 980, we grew by 280. Instead, we're multiplying or dividing by the same amount each time. In this case, we're multiplying by 1.4, by 1.4 each time.Arithmetic is all about the building blocks, and the basic arithmetic operators are some of the most important building blocks around! Operators tell us how one value should relate to another. Here are the four basic arithmetic operators: Add. 1 + 1 = 2. The result of addition is the “sum”. Subtract. 3 − 2 = 1.Solution. The common difference can be found by subtracting the first term from the second term. \displaystyle 1 - 8=-7 1 − 8 = −7. The common difference is \displaystyle -7 −7 . Substitute the common difference and the initial term of the sequence into the \displaystyle n\text {th} nth term formula and simplify.
