Question

If the ratio of the sum of first n terms of two AP's is (7n+1) : (4n+27), find the ratio of their 10th terms.

Answer 1

$\bf\large\underline\pink{Solution:-}$

If the ratio of the sum of first n terms of two A.P.'s is (7n+1): (4n+27), find the ratio of their mth terms. To find the ratio of the mth terms of the two given AP's, we replace n by (2m-1) in equation 1.
