WebJul 1, 2024 · Find the sum of the A.P. Solution: From the above equation, it is known that, a =2, d= 4- 2= 2, and a n =10 Using the above equation of sum of n terms in a AP and substituting the values, S n = 5/2 [2× 2+ (5-1) × 2] S n = 30 So, The sum of the of first 5 even natural numbers is 30 WebSolution : Let the sum of `n` terms be given by `S_n` so `S_n= (3n^2)/2+ (5n)/2` `S_1= (3 (1)^2)/2+ (5 (1))/2 =3/2+5/2=4` So `1^ (st)` term is `4` let it be a Now, `S_2= (3 (2)^2)/2+ (5 …
in an AP the sum of first n terms is 3n2/2 + 13n/2 - Toppr
WebMar 31, 2024 · Given: Sum of the first n-terms is 5n²/2 + 3n/2. To find: The 17th term of the A. P. Solution: Step 1. We find the sum of the first 17 terms. Sum of the first 17 terms is = 5 (17)²/2 + 3 (17)/2 = 5 (289)/2 + 51/2 = 1445/2 + 51/2 = 1496/2 = 748. Step 2. We find the sum of the first 16 terms. Sum of the first 16 terms is = 5 (16)²/2 + 3 (16)/2 ... WebAn arithmetic progression or arithmetic sequence (AP) is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence. The constant difference is called common difference of that arithmetic progression. For instance, the sequence 5, 7, 9, 11, 13, 15, . . . is an arithmetic progression … iop corresponding author
The sum of the first n terms of an AP is (5n^2/2 +3n/2
WebThe sum of the first n terms of an AP is (5n 2 /2 +3n/2). Find its nth term and the 20th term of this AP. arithmetic progression class-10 1 Answer +2 votes answered Sep 14, 2024 by … In AP, we will come across some main terms, which are denoted as: 1. First term (a) 2. Common difference (d) 3. nth Term (an) 4. Sum of the first n terms (Sn) All three terms represent the property of Arithmetic Progression. We will learn more about these three properties in the next section. See more In mathematics, there are three different types of progressions. They are: 1. Arithmetic Progression (AP) 2. Geometric Progression (GP) 3. … See more Webrepeatedly with the same N, one of the two values (2.5) will, with probability one, lead to long-run profits, the other to long-run losses. But which is which? The expected value of the game-the deciding factor-is 2-N( N ) N r(j), where 7T(-) is the periodic function whose first m values are the 7Tj. By itself, this representation tells us nothing. on the momentum
