Correct Answer – A

Given series are

3+7+11+15+19+23+27+31+ . . . . . .

and, 1+6+11+16+21+26+31+ . . . . . . As illustration 8.

The common differences of the two series are 4 and 5 respectively. Therefore, the series of common terms will form an A.P. with common difference 20 and first term 11.

Hence, 10th common term `=11+(10-1)xx20=191`.
