WebSolution Verified by Toppr nC r= nC n−r. The number of combinations of n dissimilar things taken r at a time will be nC r. Now if we take out a group of r things, we are left with a group of (n-r) things. Hence the number of combinations of n things taken r at a time is equal to the number of combinations of n things taken (n-r) at a time. WebTo calculate combinations we use the nCr formula: nCr = n! / r! * (n - r)!, where n = number of items, and r = number of items being chosen at a time.

For each placement in the first position there are 6 possibilities for the second position. This means there are 7 ×6 possibilities for the first 2 positions. WebTo write the Recursive formula for Geometric sequence formula, follow the given steps: Step 1 In the first step, you need to ensure whether the given sequence is geometric or not (for this, you need to multiply or divide each term by a number). If you get the same output from one term to the next term, the sequence is taken as a geometric sequence. phineas and ferb meets scooby doo
