Hello,

Hoping this is an easy fix for someone out there. I am having trouble getting excel to continue a formula I have manually typed. On my sheet titled "Input" I have values in the following cells:

G12
G13
G17
G18
G22
G23
G27
G28
G32
G33
(and so on in increments of five as per the above pattern)

On a second sheet titled "output" I would like the following:

D14 = sum of G12 + G13
D15 = sum of G17 + G18
D16 = sum of G22 + G23
D17 = sum of G27 + G28
D18 = sum of G32 + G33
(and so on up to approx. D100)

Can anybody advise of the formula to start with in D14 that I can then autofill down and will continue. My attempts so far have been unsuccessful.

Thanks in advance.
