Question

State the rules for Arithmetic Operations with significant figures giving examples​

Answer 1

An arithmetic sequence is a sequence where the difference between each successive pair of terms is the same. The explicit rule to write the formula for any arithmetic sequence is this: an = a1 + d ( n - 1 )

Example 1: 3, 7, 11, 15, 19 has a1 = 3, d = 4, and n = 5. The explicit formula is an = 3 + (n – 1)·4 = 4n – 1

Example 2: 3, –2, –7, –12 has a1 = 3, d = –5, and n = 4. The explicit formula is an = 3 + (n – 1)(–5) = 8 – 5n
