Which term describes the estimation of an intermediate value between marked values in a series?

Explanation:
Interpolation is the estimation of a value within the range spanned by two known values. When two points are marked, you infer a value between them by assuming the change between those points follows a reasonable pattern (often a straight line). This exact idea—estimating an intermediate value between known values in a series—is what interpolation describes. Extrapolation would be estimating beyond the known points, averaging gives a single overall mean rather than a specific intermediate point, and rounding changes a value to the nearest whole number rather than providing an intermediate estimate.
