WebPractice Questions. The sequence 12b, 8b, 4b is in AP. Find the sum of the first 18 terms. The first three terms of a sequence are 8, y, 18. Find the value of y so that the sequence becomes an Arithmetic progression. In an Arithmetic progression, the ratio of the 7th term to the 10th term is -1. If the 16th term is -15, find the 3rd term. WebMean is calculated by shortcut method formula as: x = A + 1 N ∑ i = 1 n f i d i. where, d i = x i - A. A = Assumed mean. x i = Class mark. N = Total number of data. f i = frequency of class mark. x = mean of group data. To calculate the arithmetic mean using the step deviation method, we first find the deviations d which are divisible by a ...
