Consider the following series.[infinity]1n6n = 1(a) Use the sum of the first 10 terms to estimate the sum of the given series. (Round the answer to four decimal places.)s10 = (b) Using the Remainder Estimate for the Integral Test, find a value of n that will ensure that the error in the approximation s ≈ sn is less than 0.0000001.n > −18n > 11 n > 6n > 0n > 18
