[コンプリート！] 1 2 3 4 ... n formula 345870-1+2+3+4+...+n formula

Sum of n, n², or n³ n n are positive integers Each of these series can be calculated through a closedform formula The case 5050 5050 5050 ∑ k = 1 n k = n ( n 1) 2 ∑ k = 1 n k 2 = n ( n 1) ( 2 n 1) 6 ∑ k = 1 n k 3 = n 2 ( n 1) 2 4Use the distributive property to multiply a n by 2 n − 1 Use the distributive property to multiply 2a_ {n}na_ {n} by 2n1 and combine like terms Use the distributive property to multiply 2 a n n − a n by 2 n 1 and combine like terms Subtract 4n^ {2} from both sides Subtract 4 n 2 from both sidesQuestion I have been looking at your Excel IF, AND and OR sections and found this very helpful, however I cannot find the right way to write a formula to express if C2 is either 1,2,3,4,5,6,7,8,9 and F2 is F and F3 is either D,F,B,L,R,C then give a value of 1 if not then 0 I have tried many formulas but just can't get it right, can you help
