Given the arithmetic sequence:
1.77, 1.92, 2.07
Determine the 31st term.
n = 31
a1 = 1.77
a2 = 1.92
d = 1.92 - 1.77
d = 0.15
Formula for Arithmetic Sequence:
An = a1 + (n - 1) d
Solution:
Substitute the given values to the formula for arithmetic sequence.
A31 = 1.77 + (31 - 1) 0.15
A31 = 1.77 + (30)0.15
A31 = 1.77 + 4.5
A31 = 6.27
Final answer:
A31 = 6.27
