Question 347682
There must be a little more information. Is this problem 
part of exercises on linear equations? If so,
given:
Let t represent the number of years since 1994.
{{{t[1] = 0}}} (1994)
{{{t[2] = 7}}} (2001)
{{{E[1] = 62.6}}}
{{{E[2] = 65.2}}}
Assuming this is a linear relation between {{{E}}} and {{{t}}},
The formula to use is:
{{{(E - E[1]) / (t - t[1]) = (E[2] - E[1]) / (t[2] - t[1])}}}
plugging in data:
{{{(E - 62.6) / (t - 0) = (65.2 - 62.6) / (7 - 0)}}}
{{{(E - 62.6) / t = 2.6 / 7}}}
{{{(E - 62.6) / t = .3714}}}
{{{E - 62.6 = .3714t}}}
{{{E = .3714t + 62.6}}}
With this equation, you can find {{{E}}} for any {{{t}}}
